OK.
This is what I have done on my desktop (main) pc.
Uninstalled everything, including Stardock Central.
Deleted all relevant remaining folders & files.
Deleted all files from C:\Program Files\Common Files\Stardock except for MCPStub.dll (could not for the life of me find the service to stop or the running process to close to unlock this file).
Re-installed Stardock Central (not viewing alpha & beta pre-releases).
Downloaded and installed Tab Launcher, tested program, program ran perfectly.
Installed virtually rest of available programs.
Ran Control Center, tested, encountered 2 access violation errors, but program then opened and ran perfectly.
I then ran Stardock Central and viewed alpha & beta pre-releases.
I installed Tab Launcher 1.13[b].002, tested program, program ran perfectly.
Ran Control Center again, tested program, program then opened and ran perfectly without any error messages.
Hope this may help for any further problems re Control Center and Tab Launcher if encountered by anyone else.
