Whenever I try to install a program I get the following 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 Ultimate - Version 6.1 (Build 7600).
I have tried the following solutions, to no avail:
Go to services.msc and start Windows Installer
When I try that, I get the error message:
Windows could not start the Windows Installer Service on Local computer. Error 5: Access is denied.
When I tried as Admin, I could not even open services.msc. It said:
This function is not supported on this system.
Deleting a second msiexec.
When I went to
C:\Windows\system32, there was no second msiexec.
Modify Remote Procedure Call Service
When I got to the Log On tab I was not able to choose Local System Account.
Reinstall Windows Installer Service by downloading MSIServer
After I merged the two files nothing changed.
Install the latest Windows Installer version.
I already have the latest version.
Run regedit. Navigate through
HKEY_LOCAL_MACHINE…SYSTEM…CURRENTCONTROLSET…SERVICES…MSIServer. Then right click on
WOW64and select “Modify.”
When I got through the steps, there was no WOW64 for me to choose.
I do not know what else to try.
