Errors after Client tool installation for BO 4.1 sp7

Hi Guys

We recently upgraded out BO platform from 4.1 sp3 to 4.1 sp7.

I ran an installation file to update all my client tools such as IDT,UDT , Webi etc.

First I tried to put an update patch which did not work, so I uninstalled all the existing client tools on SP 3 and installed sp 7 .

Now when I re-started my machine, only IDT is working, UDT does not even load and Rich client gives me this error below:

Any ideas how to fix this??

cheers
