Fixing an issue that when plugin *.dll file is deleted - it will not be reinstalled - making the file to be using KeyPath instead of registry entry

Hi Richard,

I have some complains from users that their plugins didn't work... In case they manually delete plugin DLL file - and later tried to install MSI again - it's not reinstalling the component which includes DLL file. Basically they went and deleted all files themselves - leaving all other things like Registry untouched.

The reason is that "KeyPath" is made for registry entry - so only if that one is removed it would reinstall it.

I've already solved all other files in my custom WXS so that each file is separate component with "KeyPath=yes" - but the DLL file is inside auto-generated WXS file.

Applying a change for Wix Templates.

Not commiting directly to FB 2.0 branch - just wanted to make sure you are OK with it ;)

This should work fine w/ HKLM, but HKCU usually installs to the user profile directory and you can't use a file in the user profile directory as a KeyFile, which is why it's done the way it's done.

I'm open to other suggestions :-/ Unfortunately this will break a per-user install.

Intresting... I'm using HKLM myself - and I didn't realize KeyPath doesn't work for files in user profile.

I'll try that - if that will not work... I'll remove HKCU change.

But I guess this issue is far more probable for HKLM - some users tends to go to C:\Program Files\ and delete files... While I guess avarage user will not be able to find his own profile directory - since that's hidden by default.
