This morning I came into my office to find my pc (p4, win7) apparently in a loop. the cpu usage was very high on all four processors, and the disk usage was high as well. I tried restarting the computer but there was so much cpu usage that I couldn't even type. So after 10 minutes or so, I just pulled the plug. The first problem was that Norton Internet Security stopped working. After an hour on 'chat' with Symantec, they reloaded the software for me and now NIS is working properly. But I still have (at least) two probems. (1) My RIMDeviceManager fails with an 0xC015002 error, and all my MSOffice 2007 programs fail with "The application has failed to start because its side-by-side configuration is incorrect." I unstalled all the Microsoft C++ programs and then did an MSOffice "repair" and it looks like C++ Redistributable (32 and 64-bit) were re-installed, but Outlook, Excel, etc, still get the same error. Everything I've read about fixing the problem is way over my head (and I'm fairly technical). Does anyone have a clue what I should be tracking down?
