Help stopped working

[beni.falk]

I am using SlickEdit Pro 2019 x64 (24.0.1.0) on Windows 10.
At some point the help system stopped working. That is, it shows blank screens. This occurs when I invoke help from the menu or press F1 or issue the help command from the command line.

This definitely worked until recently.

I tried reinstalling SlickEdit and it didn't help.

What could be the problem?

Thanks,

Additional information - this problem also occurs when I invoke SlickEdit Help from Windows start menu.

I also tried to manually invoke the help function from a command window:
"C:\Program Files\SlickEdit Pro 24.0.1\win\assistant.exe" -collectionFile "C:\Program Files\SlickEdit Pro 24.0.1\help\slickedit5.qhc"

and the behavior was the same.

The collection file definitely exists in that directory.

This gets stranger and stranger.

I have renamed slickedit5.qch and slickedit5.qhc to slickedit.* and I can now invoke help from the Windows command line (!).
Obviously, when I try to invoke help from within SlickEdit it complains about not finding slickedit5.qhc.

What is going on here?

Try wiping out the Qt Assistant cache.

That solved the problem.

Thanks!

By the way,  I would suggest removing this folder during SlickEdit uninstall (or install).

This happens randomly. Nothing to do with installing a new version.

I'm starting to think there needs to be a Delete Qt Cache menu item on the Help menu. You don't want to delete it all the time because Qt help builds a search database which can take a while.
