Please help - Programs won't install after Service Pack update

Hi

I recently installed the latest Windows Update for Service Pack - the install took quite a while, and I left my laptop plugged into the power supply to ensure it didn't go to sleep/power off.

I recently got 02 Broadband which came with MacAfee, however, the authorisation process didn't work so well, so I downloaded Avira Antivir - Avira installed however keeps showing the following:



So I uninstalled Avira and downloaded AVG - AVG installed but then crashed out with an error message. I attempted to download Avast! and the same happened - it won't let me install anything I've downloaded, so I'm guessing something occurred during the Service Pack update.

Any help would be greatly appreciated!

Thank you

Georgie

Hello Georgiee and welcome to the forums

I would recommend that you do a system restore to before you had the service pack:

Then I would remove whatever anti virus you had installed on your system at that time using the designated removal tool from the manufacturer's website. Take a look at this if you're unsure where to find it:

Then install the service pack through Windows Update

Then create a restore point:

Then install whatever anti virus you want

Let us know if it works!
