Catalyst has been  working for me until now. i tried opening it on version 12.11 beta, and it wont open. i removed it from my computer, using the un-installer and re-installed. still didnt work. i was trying to run 7970's in crossfire when this happened. do i need to clean install windows?

Specs:

intel core i7 2600k

Intel Z68BC mobo

2x reference Sapphire 7970's

Same problem here. I tried everything but it's won't open. I noticed something. CLI.Implementation and MOM.Implementation assembly public key tokens they aren't in assembly folder. They aren't installing from there...

Did you follow the link in the OP message? You must have the correct version of netframework.
