Can't delete registry key "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Antimalware Setup" to reinstall Microsoft Security Essentials.
I am running Windows 7. I uninstalled MSE to reinstall it. I found a registry key "Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft Antimalware Setup" that's preventing the reinstallation. I can't delete it because the "OWNER/CREATOR" has set "Special
permissions" on the sub keys that supersede the Administrator's rights. Does anyone know how to delete these keys and reinstall MSE?
Windows 7 Home Premium sp1
Manufacturer: Computer Express
Processor: Intel(R) Core(TM)2 DuoCPU
T8300 @ 2.4GHz 2.40 GHz
Type: 64-bit Operating System
Let me add that about every five web maneuvers, I get a popup directed to
I think these guys may have something to do with my problem.
As you can see, CREATOR-OWNER has "Special" permissions.
Have you tried deleting that key in safe mode? If not, please try it first. If it didn't work then go with this advanced and risky method:
Warning: This method involves editing registry which is a very sensitive thing. Incorrect editing of registry can lead to many many bad things including complete operating system crash. In addition to this risk there is also some far more risky thing involved.
So please proceed with very precaution and follow the steps word to word. If you didn't understand anything then stop and ask.
Step 2: Get PsExec.exe
Open PsTools and copy PsExec to C: drive.
Step 3: Start Command Prompt
Go to Start --> Type "cmd" in search box --> Right click on 'cmd.exe' and click on 'Run as Administrator'. This will open Command Prompt as Administrator.
Step 4: Run Registry Editor
Type this code and hit enter: C:\psexec.exe -i -s regedit.exe
Step 5: Delete that key
Navigate to that conflicting key and delete it.
Note: You are making modifications with very superior rights so you must edit registry very carefully. With these superior rights you can edit system's critical keys also which normal run of regedit.exe will not. Please be very careful.
Please come back with the results. Please mark replies as helpful/answer if they are.
Thank you PrashantKumar96! With your assistance, I have successfully deleted the persistent keys. HOWEVER, I embarrassed to report that I have
encountered the same error when I tried to re-install MSE again.
I will review the MSE installation checklist and try again. It would be nice if someone could give me an application or procedure that "steps through" each command of the installation process (like VB) so that I can see what step is encountering the internal
Does anyone know an application or code I could use diagnose my MSE installation problem?
I just had an issue with my Win 7 Microsoft Security Essentials. Windows update
would download the upgrade, but the upgrade could not install. After many
hours of searching help sites and web search engines, I finally found out
what the problem was. Somehow, Windows lost the install information
file. And without those files.......<br>
