MrGr Regarding your Hauptwerk item, above ...
I think it's only natural for some items to be placed in a user's profile folder. A different user will have different content that what you have. So his stuff will be located in his folder, not yours.
Anyway ... this is a PC (personal computer) world. That is, most computers are used by just one user. That renders the point quite moot.
In the rare case where that does not apply you can simply change the folder name (during installation) to suit your needs.
As for your other items ... I wonder why you use this forum to raise such complaints? If (as you suggest) the software publisher has no intention of releasing a remedy for a problem, then do you expect anyone here to do so?
