Error 1772

In installing 32bit with XP tried turning off AVG virus scan, tried the suggestions mentioned here http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/install-wse-30-error-1722-there-is-a-problem-with/4f40a3de-b611-4dc9-a267-e341fed7774d?auth=1

To no avail, I appreciate this might not be a DS problem but has anyone got any solutions, I really need an alternative to my outdated AutoCad and this looked so promising

TIA
