I had a windows XP home edition in my computer until I decided to install a XP Professional today and when I start the process I get that error message, I Cleaned the disk and all, tried using my XP home cd instead but still nothing happens.

I seen that I should try regedit.exe but when I put that in I get a message saying "The System Cannot execute the specified program" message.

I wish I could just go back to using my old installation but everytime I restart the compouter it enters the install process.

Any help is much appreciated.
