I have a couple of problems that seem to be related. i can not install anything.
first error when launching a setup:
The Windows installer service could not be accessed. This can occur if you are running Windows in safe mode, or if the Windows installer service is not correctly installed.
Event viewer displays:
Failed to connect to server. Error: 0x80040154
I'm also seeing error:
Windows couldn't log the RSoP (Resultant Set of Policies) session status. An attempt to connect to WMI failed. No more RSoP logging will be done for this application of policy.
loading: WindowsInstaller-KB893803-v2-x86.exe , it will install and complete successfully but nothing changes.
deleting msiexec, msi.dll, msihnd.dll and restarting
deleting the WMI files in the repository
msiexec /unregister, msiexec /regserver
Nothing works, maybe a permissions issue in the regisrty?
