i have looked at several posts about this on a few forums, one was on Bleeping computer, the problems for those individuals were fixed, i followed the instructions given and they did not work for me.
as a result, i have formatted my computer and re-installed my Windows XP Professional SP2 OEM disc which helped for a margin of about 5 minutes, cmd and regedit did work for that time something had changed within the 5 minutes to stop these programs from working.
i resulted to renaming the cmd.exe to command.exe and regedit.exe to reg3dit.exe, they are currently working when i type in those names on the run command, although the programs i am installing don't recognise the change and still can't install as a result.
i have now become a member of this website to seek additional information and help.
