Failure to Launch

Joris de Ruiter - You star!!! Disabling the Dropbox context menus works. Thank you so much!

Thanks for sharing the info, Joris! Disabling all Dropbox shell extensions per your instructions seems to have fixed the problem. Strangely, I still have Dropbox context menus and icon overlays. It took a couple of reboots, but it seems that NPP launches just fine now, and I didn’t have to uninstall anything or disable Explorer Lite. Good luck!

I’m having the same problem with the explorer plugin. Any update on a permanent fix?

I’ve just manually updated Dropbox to 8.4.21 (released early today, 24/Aug) and that seems to have put things right. Dropbox does not seem to pick up small increments automatically so I went through www.dropbox.com

I have cured ‘failure to launch’ on Windows 10 64-bit, WIndows 7 64-bit and Windows 7 starter, so it looks promising. I have tried as many plugins as possible to try and provoke failure but so far it’s looking good.

My Dropbox version is now at 8.4.21 and the NPP Explorer plugin issue appears to have been fixed.

If you move explorer.dll from disable then you have to give permission to current user to access and it will fix :)

Same hapened to me after Avast update. Remove “plugins” folder and problem solved.
Suspect on avast and LigthExplorer plugin combination, just becouse explorer plugins seems to have something to do.

Same problem here.
I use DriveOnWeb instead of Dropbox, disabled all respective shell extensions, problem remained.
I use 360 Total Security instead of Avast, disabled the anti virus program, problem remains.
Any ideas what else might interfere with Explorer and LightExplorer plugins?

Hi,
I come back to this thread because I’m facing the same problem ‘failure to launch in browser’. By now I have tried several things. Dropbox I do not use, so that cannot cause the problem. Today I uninstalled the ‘normal’ version of NPP, and installed the portable one (on a stick), but does not help. Debug info looks like this :

Notepad++ v7.5.4 (32-bit)
Build time : Jan 1 2018 - 01:47:45
Path : G:\Notepad++Portable\App\Notepad++\notepad++.exe
Admin mode : OFF
Local Conf mode : ON
OS : Windows 10 (64-bit)
Plugins : DSpellCheck.dll NppConverter.dll NppExport.dll mimeTools.dll

Logging in as admin doesn’t help either. Anyone who knows how to fix this ?
