@OddSquirrel Could you please try the following steps and see if this fix your issue :

1. Uninstall PowerToys.
2. Ensure that C:\Program Files\PowerToys folder is deleted. If not, manually delete it.
3. Install Powertoys Version=0.21.1

Please follow the below steps in case this still doesn't fix your issue :

1. Upload log files located at %userprofile%/appdata/local/microsoft/powertoys/powertoys run/logs
2. Upload PowerLauncher.deps.json located at C:\Program Files\PowerToys\modules\launcher.
3. Check if wox.dll is present in C:\Program Files\PowerToys\modules

Removing the folder C:\Program Files\PowerToys manually fixed the problem for me.

@enricogior This issue is happening because powerlauncher is trying to load older version(1.0.0.0) of the dll. Starting Powertoys version=0.19.0, these dll's are supposed to have same version as powertoys. Deleting installation folder at C:\Program Files\PowerToys and reinstalling powertoys seems to fix the issue. I haven't been able to repro this issue. Can you please help with this?

Similar issue has been reported in #6386 and #5471

@somil55
we need to know what was the sequence of installations.
When PowerToys is uninstalled, it's not supposed to have anything left behind. If something is left behind we should know which files were not deleted to have something to working on.

[crutkas]

isn't #5471 the same issue.

[somil55]

@crutkas #6386 and #5471 are both similar to this.

@stlorenz
when you first installed 0.21.1 did you manually install it using the .msi or the .exe, or what it an autoupdate?

[stlorenz]

I did a manual install via the msi. Autoupdate didn't seem to work for me.

[enricogior]

@stlorenz
thanks, that might have been the problem, the .msi is not supposed to be used for updates, we provide it for IT specialists that have specific requirements to automatically install PowerToys.

@crutkas we should consider stop releasing the .msi as it is and figure out a way to release it so it won't be used by users.

[stlorenz]

@enricogior Yes, thats why I always use the MSI Variant because we distribute it then for all our machines.

[enricogior]

@stlorenz
starting with 0.21.1 we added installation flags to the .exe to facilitate the transition from the .msi
https://github.com/microsoft/PowerToys/tree/master/doc/devdocs#supported-arguments
are those good enough for your installation scenario?

[crutkas]

@stlorenz would love to sync with you on how you feel we can still support the IT route but not cause confusion.

[stlorenz]

@enricogior @crutkas The silent flag in the *.exe is fine for our scenario an we weill use this in the future instead of the *.msi.
Thx for pointing this out.

duping against #5471
