Dear Farshad,
thank you very much for your help.
I tried some more with my installation, but
i think the Delphi XE2 Update 4 was the Problem and
killed something.
Today i installed a complete new Delphi XE2 with included Update 4
and then i could install the uniGUI without any problems.
Then i tried to install all other Software packages like
TMS, LMD, Clever Suite, Next etc. everythink works fine.
Afterwords i deinstalled the uniGUI and installed it once more,
and it works.
Since october last year, when i found your uniGUI Components i'm
a fan of them - thanks for your perfect work
