On the download page, when I click on the 64bit installer, I get an error message:

Error 503 Backend fetch failed

Depending upon the magnitude of the large filesizes you are talking about, your move may have been a good one (Notepad++, even 64-bit, is limited in the size of file it can open).

I have done this several times since my original post - thanks for the changes to accommodate this.

However in this case I then ended up using the View Source command in Internet Explorer and got this error:

[Window Title]
C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe

[Content]
Windows cannot find ‘C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe’. Make sure you typed the name correctly, and then try again.

[OK]

Turns out the 32-bit installer had set this value at some point in the past in the registry and it was not modified or removed when I ran the 64-bit installer:

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer\View Source Editor\Editor Name
(Default) = C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe

Since the 32-bit program is removed, there is no C:\Program Files (x86)\Notepad++\nppIExplorerShell.exe

Further there is no 64-bit version of nppIExplorerShell.exe in C:\Program Files\Notepad++

You can, of course, replace the default value with “C:\Program Files\Notepad++\notepad++.exe” and IE will launch npp as the viewer although it will likely throw a security warning.

The bug is still there in version 7.1.

:)
This is working and the installtion will be i the folder C:\Pub
npp.7.1.Installer.exe /S /D=C:\Pub
:)

:(
The x64 version of 7.1 is not working.
The installtionfolder will be C:\Program Files\Notepad++
npp.7.1.Installer.x64.exe /S /D=C:\Pub
:(
When will you fix this bug???

Any suggestion about the message in this box?

I think a simple message would suffice, something along the lines of: “Would you like to keep your custom settings?”

I’ve seen some uninstallers ask the user whether they’d like to keep their configuration files. Not sure how easy this would be.

I’m doing this feature. it’ll keep config.xml, stylers.xml, langs.xml, contextMenu.xml and themes files (all the files in %APPDATA%\notepad++).
A message box with Yes and No buttons will be launched during the uninstallation. for asking users if they want to keep their user data.
Any suggestion about the message in this box?

This was on Windows 10 Version 1607, but I suspect that ain’t going to make too much difference.

thanks in any case for the port to 64-bit.

come on, it’s brand new - plugins need to be developed/recompiled etc…
and even without any plugins, npp is still a fast and powerful editor.

in theory yes, but at the end it depends how many ram can be used.

I have been using Notepad++ to convert large files of UTF-8 text data to UCS-2; they start around 450,000,000 bytes size and end up about 900,000,000 bytes. (There are other ways to do that, which I don’t have access to in my test environment, e.g. PowerShell 5.0 has capabilities.)

Notepad++ saves the larger file but then cannot open it - I assume this is not a flaw in my environment. I would like to be able to open the file and save it back to UTF-8. This should be identical to the original file, but that is what I want to test.

The plugin manager has been left out of the 64-bit version of Notepad++ because a 64-bit version of the plugin manager does not exist. And you are correct that very few 64-bit plugins currently exist.
