Anyone care to talk about Windows Installer?

Question

Acer Windows Vista

OK, so I get this error when I am trying to download a program: Error 1719 Windows Installer could not be accessed. I do some research that indicates it might be caused by Windows Defender. I go to Windows Defender which is turned off....and none of the settings can be changed due to an "unidentified problem." The same with Windows firewall.

I have Avast and Comodo....

Then, I read something about a "Group Policy."....???

Answer 1

Stupid questions I'd need to ask.. Did you download this installer and choose run from the dialogue, or is downloaded into a folder say your desktop and then run. Have you tried installing in safe mode..next would be have you downloaded Windows Installer 3.1. and ran it?

Answer 2

listen if u have Avast and Comodo, u dont need windows defender, delete the program, it will fix the error.

Answer 3

Install XP...and wait for Microsoft to get their act together (but don't hold your breath).

Answer 4

Sounds like a virus, or OS corruption. Do a scan then a system restore.
