Well Lets see. There are no crash logs... Nothing is crashing. the program never starts.
System info? Other than Windows 7 (x64bit) not much else needed. The link you sent for Cleaner is for Creative Suite, which as I stated in my first post does not apply for me as I only have CS6.
The other link you posted on Working with your Operating system also does not help and does not have anything to do with my problem.
Just thought I would pass on that I had several chat sessions with Adobe on this issue with no resolution. It is a known issue, but what causes it can be hard to find. I have posted a link below on some things Adobe had me try. For me setting up a new account did not work.
In my case I think what happened, is I have W7 program files installed on a secondary drive. At some point my system reverted back to installing programs on my primary drive. I suspect, some certificates were not installed in the correct location. Even a new Admin account had no luck.
However, it never hurts to refresh a computer install as I had been running several years in ths configuration. A new W7 install resovled the issue and as usual, load times are improved
