I am trying to repair my nephew's computer. I ran several anti virus programs to find the problem, and found that the "rundll32.exe" appears to have been corrupted. I tried several things that did not work, so I decided to take his computer home with me where I would have more time to work on it. After 10 plus frustrating hours, I took my XP Installation disc and did a repair. After the repair function was completed, it asked for the PRODUCT CODE. I put in the product code from my disc, and it rejected the code, so I called my nephew, and used his product code, it was rejected also.
I have tried jellybean, and get the error message "out of range". I can not get into windows until I can satisfy the product code issue. I have used Bart PC, and can access the hard drive through dos, and have been able to run regedit, but do not know how to locate the product code.
Can anyone help with this?
