Cycrow did you ever get plugin manager to work with default steam install path? As in Program Files (x86) or other system paths.
I just remembered it used to be impossible on win7 to get it to work if game was installed in program files. And I just did it again.... ughh.
edit:
Not sure how helpful this will be to anyone. But I only just now noticed Steam finally added option to set a different steamlibrary location.
Open steam and log in etc. Click Steam>Settings>Downloads+Cloud and all the way down you will see "Steam Library Folders" in here you can add additional "path" to install Steam content. Folder MUST be empty.
So for instance if you are installing all your games into C:\Games navigate there and click add new folder. By default it names it SteamLibrary doesn't really matter since its only the initial folder. Content will be placed further in. In pretty much identical manner to installing it in the Steam location.
So in the end you end up with C:\Games\SteamLibrary\SteamApps\common\X3StoleYourLife
Most people probably already found this long-overdue option but for me I just found it lol... I don't like dealing with steams @#$% drm or code integrity checks or their automatic permanent and undisputable VAC bans(which have been only revoked when a few thousand people get banned due to their ****** coding and they just can't afford to maintain "corporate monkey attitude").
Hope it helps someone
