Hope this helps...
|I had the same problem..... When ever i tried installing any program this error code came up... I downloaded various "Quick computer fix" program's and they didn't help at all. I researched the problem and found that if i set my account to full access it should work... It didn't. But then i defragmented and did a disk clean and the problem was fixed. I'm on vista by the way.|
