Plugins > Open Plugins Folder: Nothing happened. File Manager did not open.

I also fixed this by this page:
https://support.microsoft.com/en-us/help/929833/use-the-system-file-checker-tool-to-repair-missing-or-corrupted-system
FYI.

It really miraculously solved the issue.

I am glad it solved the issue for you.

But it wasn’t a miracle: if the plugin has a dependency on the MSVC++ Redistributable, then that dependency must be satisfied in order to run. Unfortunately, plugins don’t always advertise that requirement.

I have submitted an issue #12 and PR #15 to fix oviradoi’s README to include that requirement.

So I decided to upgrade and downloaded the Microsoft Visual C++ Redistributable for Visual Studio 2015.

I downloaded the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 for x86 from
https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads.
It really miraculously solved the issue.
Thanks all for the great help!!

ProcMonitor will say which DDL notepad++ querys on plugin loading.

Here you are.

Yes I did. Please see above.

Sorry, it looked so much like the post above that I didn’t notice the picture was different. My bad.

It does not look like Windows is trying to load the wrong DLL when Notepad++ requests Explorer.dll / MyExplorer.dll. So, that’s good news … but also not helpful, unfortunately. :-(

My next guess would be that @guy038 is on the right track: try to download the most recent “Microsoft Visual C++ Redistributable”: I believe that this MS page has the most recent versions of the redistributables. Since you are on 64bit OS, but using 32bit applications, I would suggest installing both the x86 and the x64 versions from the 2015/2017/2019 section at the top.

If that isn’t sufficient, since you do have a 64bit OS, try downloading the 64bit Notepad++ portable zipfile, and unzip it to your desktop. Try to install the Explorer plugin in the 64bit (using Plugins Admin), and see if that one works better for you.

And please make sure you try my suggestion #2 of renaming the DLL and its folder.

Yes I did. Please see above.

Sorry to answer only now, but my wife and I spent the big weekend of May 1st doing some interior renovations, in our living room !

I also got problems with the plugin explorer.dll ( v1.8.8.0 - x86 - 222,720 bytes ) !

When I started N++, I was told that This application could not be start as MSVCP140.dll could not be found ! I started searching with the Dependency Walker software and it happened that all the following DLL were missing to get explorer.dll to work properly !

************************************| Log |*************************************

Error: At least one required implicit or forwarded dependency was not found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

However, after download and installation of the missing dll, either, in system32 folder or in ...\Plugins\Explorer, I always got the same message This application could not be start as MSVCP140.dll could not be found :-((.

Luckily, the next day, I found out the solution ! As my Win WP SP3 laptop is quite an antiquity, when rebuilding the OS, after a C partition crash, in 2018, I simply had installed the Microsoft Visual C++ 2013 Redistribuable x86

So I decided to upgrade and downloaded the Microsoft Visual C++ Redistributable for Visual Studio 2015. As the requirements include Win XP SP3, even if VS2015 is not present, and that some hardware specifications were OK, I ran the executable and restarted my laptop.

And…, miraculously, after starting notepad++, no more error message and the Explorer plugin was well installed and fully functional ;-))

OP is doing too much thinking and this is a problem because his thinking is counter-productive to the thinking of the people trying to help him.

OP needs to do (exactly and only) what the helpers are suggesting, and report back clear results.

That’s the only way this is going to get solved for the OP. My 2c.

I happen to have another tool Process Hacker which can also find dlls.

I don’t think this is the same goal.
ProcMonitor will say which DDL notepad++ querys on plugin loading.
Process hacker will say which one is in use but in your situation , explorer.dll is not loaded, so it’s not in use. You’ll wont find it in process hacker

Here is a screenshot of procMonitor which could be tricky to use.

I happen to have another tool Process Hacker which can also find dlls.

I meant the same message except the path.

I’m sorry for misunderstanding.

INFO: Could not find files for the given pattern(s).

I thought it might show something else, which would have made it easier to debug. But alas, it did not.

Please make sure you try @cmeriaux’s suggestion of procMonitor, which can precisely identify the location of the DLL Notepad++ is really trying to load. And please make sure you try my suggestion #2 of renaming the DLL and its folder.

>where explorer.dll
INFO: Could not find files for the given pattern(s).

It gave the error message for c:\notepad++\plugins\explorer\explorer.dll when you tried to install it while running C:\Users\Carlos\Desktop\npp.7.8.6.bin\notepad++.exe? That doesn’t seem right to me

I meant the same message except the path.

https://docs.microsoft.com/en-us/sysinternals/downloads/procmon

The same message.
c:\notepad++\plugins\explorer\explorer.dll

It gave the error message for c:\notepad++\plugins\explorer\explorer.dll when you tried to install it while running C:\Users\Carlos\Desktop\npp.7.8.6.bin\notepad++.exe? That doesn’t seem right to me: the one on your desktop shouldn’t know anything about c:\notepad++. Are you sure when Notepad++ re-launched after you installed the plugin in your desktop copy that it correctly ran the desktop copy again?

Further, I like @Ekopalypse’s theory: your Notepad++ is somehow finding a different explorer.dll. Two experiments for that, using your desktop copy of Notepad++ (we’re still trying to keep things independent of other settings and plugins that might be interfering):

1. From a command prompt (cmd.exe), you could try where explorer.dll: if there’s an explorer.dll in your path (that it would thus possibly find before going to the plugins\explorer\explorer.dll), the cmd.exe where command might tell you about it.
2. Go into desktop`npp.7.8.6.bin\plugins`, rename the folder explorer to MyExplorer and the dll that was explorer\explorer.dll to MyExplorer\MyExplorer.dll. Close Notepad++. Run the desktop copy of Notepad++.

unfortunately, that doesn’t tell us what went wrong. Were there error messages?

The same message.
c:\notepad++\plugins\explorer\explorer.dll
The specified module could not be found.
explorer.dll is not compatible with the current version of notepad++.

Could it be that it finds another explorer.dll first?

Thanks for running the experiment and giving the debug info.

And it can’t work either!

unfortunately, that doesn’t tell us what went wrong. Were there error messages? If so, screenshot them and include them, please. If no error messages, what exactly happened when you tried? Be as explicit as you can, telling us about every click or keystroke.
