The entry CachePath has a neat little entry:

A custom path where the Windows GUI stores a cache of the application definition to increase the startup time. 

My best bet is that this is something you would not like to set, because, well, it increases your time waiting on starting up the app right?

Now to my probable problem: We’ve got it set to %temp%\awesomeness_app 

That location is not restricted for reading, writing etc… Can it be that for some time now this is not working anymore, because it (tries to) write its cache in the same directory as where the executable is stored?
