      I’m having Win10 Ent.
      I had mistaken and I Installed x86 version of notepad++ instead x64 version.
      So I Uninstall this version and Install correct version for x64 (64bit) .

      After Installation I notice that files couldn’t registering as the default application with notepad++
      I tried to Replacing all C:\Program Files (x86)\Notepad++ references by C:\Program Files\Notepad++ in registry but this didn’t fixed the problem.
      I also tried to Uninstall and run CCleaner to delete all the history data , reboot and Reinstall (x64) but this didn’t fixed the problem either .

      Please How to fix it ? Is there any Cleaner tool to delete all the history data from previous installation ?

      Thanks

        @Shamay-Moti,

        Looking at this thread, it’s usually solved by the registry edits. Those were all the right actions.

        My initial guess would be that you missed a reference to the x86 version somewhere in the registry… but that might not be it. That thread mentioned there were quite a few locations.

        If you right click on a .txt file (or other file extension that’s relevant) and RClick > Open With > Choose Another App > Look for another app on this PC, and browse to your 64bit notepad++.exe, does it open correctly? (I know this doesn’t solve the problem yet, but it’s a good next step in the debug)

        What is your Notepad++ > Menu > ? > Debug Info for the 64bit NPP?

            Thanks for confirming the Debug Info…

            What happens if you use the “Open With” I mentioned yesterday?

              from the list open with --> i don’t see notepad++
              If I tried to click on "choose another app"and look for notepadd++ and I choose manually the application notepad++.exe --> but nothing happen - the file couldn’t open .

              I tried again to do the following steps:
              1- Uninstall all versions of notepad++
              2- Restart the Windows
              3- Run CCleaner for registry – to clean all unnecessary data .
              4- Run “Regedit” and look for " notepad++" and delete all the keys
              5- Restart the Windows
              6- Install Notepadd++ version npp.7.5.6.Installer.x64.exe

              ** The problem was not resolved **

              It is very frustrating and I would appreciate more ideas for solving the problem

                @Shamay-Moti,

                I understand your frustration.

                Since you cannot seem to OpenWith, even when you manually select the 64bit notepad++.exe, another thing I would try is the following series of experiments using the Windows “Run” dialog: type Win+R (hold down the Windows Key and type R), which should bring up the “Run” dialog. (Or click the windows/start menu, type “run”, and select the “Run: desktop app”, which should also show the “Run” dialog.)

                1. In the “Run” dialog, type "c:\Program Files\Notepad++\notepad++.exe" (with the quotes), then ENTER, and make sure it properly runs the 64bit NPP. Close NPP. – this will tell us whether Windows can actually run the executable from its installed location
                2. Open the “Run” dialog again; this time, "c:\Program Files\Notepad++\notepad++.exe" "c:\Program Files\Notepad++\readme.txt". (Still with the quotes: we need to protect against the spaces in the directory name.) Does it open the NPP readme file? Close NPP. – This will tell us whether it can properly open a file from a command line.
                3. Open the “Run” dialog again. This time, try to open the same file that you tried with the manual OpenWith earlier, using "c:\Program Files\Notepad++\notepad++.exe" "c:\path\to\whatever\file\didn't\open\filename.txt" – maybe there’s something else preventing Notepad++ from opening certain files, but not its own readme.txt.

                Other questions: is it only one or two files, or any file, which refuses to open when you try OpenWith and manually browsing to notepad++.exe? Have you tried a variety of file locations, or are they all in the same approximate location (all in the same \\path\to\network\location? All in your My Documents? All in the same Dropbox folder? Or have you tried a variety of locations on the drive?)

                Finally, if all else fails: is there a reason you cannot use the 32bit Notepad++? Because 32bit NPP will work on a 64bit OS. But if you are trying to edit a huge file, or if you need a plugin that’s only available on the 64bit version, then those would be reasons to only use the 64bit version.

                  Hello Peter,
                  Step 1: working Okey !! it’s mean i have version 64bit as we expect.
                  Step 2: Working okey !! Readme.txt file succeed to open with Notepad++
                  Step 3: Working okey !! My file XYZ.txt succeed to open with Notepad++

                  My goal is to open the files (TXT , LOG …etc) automatically with notepad++.
                  If i try to open *.txt file and click “Right click” on the mouse and choose “open with” i don’t see notepad++ option .
                  If I click on “choose another apps” and choose the option: “look for another app on this PC” and go do : “c:\Program Files\Notepad++\notepad++.exe” nothing Happen !! the notepadd++ couldn’t open !

                  I also tried to choose from the Notepad++ option “Setting” --> "Preferences --> “File Association” --choose TXT But it did not work either .

                  I think there is something wrong with registry due to version 32-bit (x86) was installed before .
                  :-(

                    On Win10 the following works for me.

                    • open File Explorer
                    • right click a file, e.g. temp.log
                    • select Properties at the bottom of the list
                    • click the Open with: Change button
                    • select Notepad++

                      I know your goal was the automatic-opening… I was just seeing whether windows could find notepad++.exe at all… it
                      can.

                      When the explicit Run-dialog versions work, but the manual Open With > Look for Another... does not, even when you point it directly at the 64bit executable. I tend to think that you might have missed one of the registry entries, especially ones where the key (in the left pane) is named notepad++.exe – there might be some data/value pairs under that key (or one of its subkeys) which you missed

                      When you searched your registry, did you search for “notepad++” or “notepad++.exe”? Because there are a few entries that might not have the .exe extension.

                      I have 32bit installed, not 64bit, so I cannot tell you what a “working 64bit install” looks like. (Some of my favorite plugins are still only 32bit, so I haven’t permanently upgraded to 64bit… though I have a portable version for the rare instances I need the 64bit functionality, like huge files.)

                      But in my registry, here are some of the instances of Notepad++ that I could find:

                      • HKCR\*\shellex\ContextMenuHandlers, includes ANotepad++64, which includes (Default)={B298D29A-A6ED-11DE-BA8C-A68E55D89593}. But if I go to that handler
                        at HKCR\CLSID\{B298D29A-A6ED-11DE-BA8C-A68E55D89593}\InprocServer32, I see (Default)=C:\Program Files (x86)\Notepad++\NppShell_06.dll – so it’s a reference to a DLL, rather than an .exe… maybe you missed that one for conversion from x86 to 64bit.
                        • also found in HKLM\SOFTWARE\Classes\*\shellex\ContextMenuHandlers\ANotepad++64 and HKLM\SOFTWARE\Classes\CLSID\{B298D29A-A6ED-11DE-BA8C-A68E55D89593}\InprocServer32 – I believe if you change the first, the HKLM version will automatically update (or vice versa)
                        • you may have other CLKID associated with it, as well…
                      • You probably found HKCR\Applications\notepad++.exe and all it’s subkeys and data/value pairs
                      • I have some instances in HKCR\Local Settings\Software\Microsoft\Windows\Shell\MuiCache, but they all include the notepad++.exe, so you probably found them (and MuiCache just lists recently used applications, which shouldn’t affect anything anyway)
                      • HKCR\SystemFileAssociations\... hierarchy has some subkeys with notepad++.exe: ...\text\, ...\txtfile
                      • HKCU\Software\Classes\Applications\notepad++.exe\ has a hierarchy you’ll want to check
                      • HKCU\Software\Microsoft\Windows\CurrentVersion\ApplicationAssociationToasts mentions with notepad++.exe with some extensions, as do the HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.***\OpenWithList, where .*** matfches the extensions from the Toasts…
                      • Skipping some that are HKLM links…
                      • HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\notepad++.exe: I didn’t see an App Paths earlier, so I don’t think it’s a link…, though it looks similar to the HKCR\Applications\notepad++.exe…
                      • a bunch in HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\..., which are for various installers (and thus irrelevant to file associations)
                      • some in HKLM\SOFTWARE\Patchlink.com\Discovery Agent\NativeScan\1fdd33bf-f7e2-4ba2-b49c-578375c7c250 … I think that has to do with when you install new versions… and none of them seem to have a path associated
                      • there’s also HKLM\SOFTWARE\WOW6432Node\ versions of some of the other HKLM\SOFTWARE instances

                      (HKCR = HKEY_CLASSES_ROOT, HKCU = HKEY_CURRENT_USER, HKLM = HKEY_LOCAL_MACHINE. The ones in HKLM are usually linked to equivalents in the HKCR hierarchy)

                      I cannot guarantee this didn’t miss some that were important to you… but doing a more detailed search of the registry, like I just showed, is what I would do next, if it were my system having the issue.

                        there are many oכ registry keys , it’s impossible to go over all of them

                        The solution should come from the R&D people of Notepad++ .
                        I hear about many similar cases in many people around the world

                        R&D need to release Cleaner tool (or patch) in order to clean the registry and rebuild all the keys for the 64Bit software .

                        How can we ask the Notepadd++ R&D to request to develop such a tool to solve the problem

                            Thanks, PeterJones
                            Issue solved!

                            I took a Clean VM machine and install from scratch “notepadd++ 64 bit” and took all the keys from the registry and add it to my computer.
                            export & import (I tried with 3rd party software but I didn’t find something good to do this work)

                            There were nearly 50 places I added*
                            keys for example :

                            [HKEY_CLASSES_ROOT\Applications\notepad++.exe]

                            [HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell]

                            [HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell\open]

                            [HKEY_CLASSES_ROOT\Applications\notepad++.exe\shell\open\command]
                            @="“C:\Program Files (x86)\Notepad++\notepad++.exe” “%1"”

                            [HKEY_CLASSES_ROOT\CLSID{B298D29A-A6ED-11DE-BA8C-A68E55D89593}]
                            @=“ANotepad++64”

                            [HKEY_CLASSES_ROOT\CLSID{B298D29A-A6ED-11DE-BA8C-A68E55D89593}\InprocServer32]
                            @=“C:\Program Files (x86)\Notepad++\NppShell_06.dll”
                            “ThreadingModel”=“Apartment”

                            [HKEY_CLASSES_ROOT\CLSID{B298D29A-A6ED-11DE-BA8C-A68E55D89593}\Settings]
                            “Title”=“Edit with &Notepad++”
                            “Path”=“C:\Program Files (x86)\Notepad++\notepad++.exe”
                            “Custom”=“”

                            “LastAccessedTime”=hex(b):10,4c,68,25,b0,f4,d3,01

                              @PeterJones I was having this problem too, and I’d thought that I had to use the 64bit NPP with my 64bit OS, so when I read your suggestion I uninstalled the 64bit and installed the 32bit NPP, but I still can’t associate the TXT file type with NPP. I can open individual files in NPP but when I try to make the association nothing happens. Any suggestions?

                                You most likely still have something wrong in the registry. Unfortunately, uninstalling and re-installing doesn’t always fix the registry issues.

                                Personally, if I have association problems, I just go into the .txt entry, see that it points to txtfile or similar, and go to there, add a new verb, and then set the default verb to that new verb. All the details you need are contained within this thread. (Two notes: First, registry editing is something that is technically taking a risk every time you do it; I have never bricked my PC by doing a registry edit, and have always been able to fix any problem that I introduced… but some people are more worried about such things than I. Second, after most manual registry edits, unless you have a utility that can send the right Windows messages to refresh the environment, you need to at least log out and log back in, and possibly even reboot, to get the registry changes to take effect.)

                                  I just fixed this on my PC. Here is what I did:

                                  1. Browse to the location of Notepad++. Copy the directory. Mine was

                                  “C:\Program Files\Notepad++\notepad++.exe”

                                  1. Run CMD as administrator.
                                  2. Create a new file type to associate with file extensions. This command for me was…

                                  ftype nppfile=“C:\Program Files\Notepad++\notepad++.exe” %1

                                  1. Associate your file extension with the new file type. The command was…

                                  assoc .nfo=nppfile

                                  Now when I double-click on .nfo files it opens them in notepad++. Hope it works for you!
