The system administrator has set policies to prevent this installation

benjetson · 01 Apr 2012

On some installers, when I attempt to install software, I will get an error that reads "The system administrator has set policies to prevent this installation." I have seen this error multiple times, and it only appears on certain installs. Some installs it appeared on were Predator (See Here), and Heatwave (See Here).

I find this error frustrating, and have not yet figured out what causes it.

Welcome to SevenForums benjetson!

Is this a system issued by an employer? These messages usually present themselves when you are trying to modify settings/registry/system files that have been protected by the system administrator.

If this is your system, try running sfc /scannow from an elevated command prompt. Run this THREE times if errors are found. Restart the system after each attempt.

If the issue persists, you can attempt a repair install.

Brink has created a great tutorial that has instructions for a proper repair install. See the link below

Nope, this is my home PC, running W7 Pro 32x. I'll try those solutions out, and post the results.

You need to reset group policy settings. To do this, follow this tutorial from sevenforums:Local Group Policy - Reset to Default

I've reset the group policy settings with no luck, now I'm trying to do the system scan/verification command line solution.

Same error after the command line scans, ran it four times with reboots inbetween. It did not find any errors after the first scan. I really don't have time to to a repair install, is there another solution??

Try to system restore.

I did a restore to about 2 weeks back with no results, I read here in a similar thread that it may have something to do with the "Software Restriction Policies" (SRPs) - See Here I have not set any SRPs to my knowledge, is that worth investiagting?

*Edit*: Could it have anything to do with my antivirus, Microsoft Security Essentials?

Do you have a system image from back when the system was working ok? If not, then try creating a new user account. Also, download and install malwarebytes. Permission issues is a good sign of a virus. Here is the download link to malwarebytes:Malwarebytes Anti-Malware - Download.com

I have MalwareBytes, I scanned, nothing was detected as malicious. I'll create a new user account and try.

**Edit**: I've tried installing this from the built-in administrator before, and got the same results.
