Hint: Download and install it manually, admin, safe mode, etc.
I am looking at a friends computer running XP Pro with SP3. There are two users, in one user I can install the programs fine, but in the other I get NSIS Error Error Loading Installer. I have scanned system with: Avast Boot Scan, Malwarebytes & after uninstalling Avast I ran combo fix then installed AVG & ran that All cleared. I then tried to run Microsoft Fix it & it failed & I got the following messages in two small pop-up windows:
One with the heading Extracting File - Verifying File - windows xp-kb926139 v2-86.ENU
Next with the heading: Extraction Failed with subtext: The filename, directory name, or volume label is incorrect.
Can anybody help as this has got me stumped. Although I know I can just delete the user as the user is not the administrator, but I do not like to be beaten by a problem, without trying every possible solution.
