Thanx for helping.
I have a windows 7 64-bit OS. With intel core i7-2670QM CPU @ 2.20 Ghz and 16 GB (ram)
I have an adobe cs6 master collection. Since I can't access AE, I can't say what version it is, but the file number is: 6.0.335.0
It has always worked. I never had a problem before. I work often with Photoshop, and less with after fx, and premiere, still those 3 are the ones I use the most, from the entire suite. A few days ago out of the blue, AE stopped working. I had it installed 3 weeks before and by then it did worked. Since I newly bought a bigger hard drive, I had to format/ re install everything. After that, the only program from the cs I can really say it worked was photoshop.
Now when I open AE all I get is the following message:
AfterFX.exe - System Error
The program can't start because .DLL is missing from your computer.
Try reinstalling the program to fix this problem.
I tried formatting the pc and reinstalling windows 7 with all updates, and with out any. With and without internet connection. And so far nothing. The only thing completely different now, is that I have a bigger non ssd hard drive.
