Starting yesterday, I've encountered a major problem with my year-old computer. Whenever I try to install or uninstall a program or even a Windows Update, I get the error:
“The Windows Installer Service could not be accessed. This can occur if the Windows Installer is not correctly installed. Contact your support personnel for assistance.”
I am running Windows 7 Professional 64-bit Service Pack 1. I have tried the following solutions, to no avail:
1) Go to services.msc and start Windows Installer.
When I try that, I get the error:
“Windows could not start the Windows Installer Service on Local computer. Error 5: Access is denied.”
2) Un-register and re-register the Windows Installer using Command Prompt.
This had no effect at all when tried.
3) Run sfc/scannow from Command Prompt.
I tried that and it said there were no integrity violations.
4) Install the latest Windows Installer version.
I already have the latest version.
5) Run regedit.exe. Navigate to HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/services/msiserver then right click on WOW64 and select “Modify.”
I do not have "WOW64" in msiserver
6) Delete C:\Windows\system32\msiexec.exe and restart.
I recieve a message telling me I need permission from myself to access the file in order to move/rename/delete it.
7) Re-install Windows Installer Service by downloading MSIServer
I merged the file, but it had no effect.
So here I stand: stumped. This is clearly a common problem, but no one else's solution has worked yet. Please, throw all of your ideas at me. Thanks.
