Windows Installer

When I try to run a setup that uses Windows Installer, I get an error.
"The Windows Installer service could not be accessed.This can occur if you are running Windows in safe mode, or if the Windows Installer is not correctly installed." Screenshot: Can anyone help me? I am running Windows XP Professional SP3 by the way.

Microsoft's Knowledge Based guidance may help;

I noticed a weird thing there! Your error message mentioned XP being in Safe Mode. That KB article says the error could be because XP is in "Normal Mode"!

It's good to see that there are humans at Microsoft, and they are prone to mistakes just as we all are. Happy

I dont think it would help because on the e Click SYSTEM in the Group or user names list, and then select the Full Control check box under Allow in the Permissions for SYSTEM box step, the Full Control was already checked off. Thanks though!

it seems a rapair install of Windows is required.

That Microsoft KB acknowledges that option if their guidance fails to resolve the issue.

"If the problem is not resolved, repair Windows XP. For more information about how to repair Windows XP, click the following article number to view the article in the Microsoft Knowledge Base:
