The Windows Installer Service Could Not Be Accessed
Windows 7/64 HP Sp1 - I was brought 2 systems today with the above error, ie unable to install or uninstall software. Both system use different AV (McAfee in one case and AVG in the other). I have not seen this error on Win 7 before, then 2 come in a row!
In the first case the client had tried to restore the system without success. I tried to restore further back but was rewarded with a bsod 6B - system repair fixed that. I tried all 4 suggestions from MS - as per

In the first case the client had tried to restore the system without success. I tried to restore further back but was rewarded with a bsod 6B - system repair fixed that. I tried all 4 suggestions from MS - as per http://support.microsoft.com/kb/2642495 - none resolved the problem - in fact the Windows Installer service is set to auto and was started. Chkdsk c:/r reported no errors, neither did SFC /scannow. Virus scan did show one filre on the D drive which was removed (Combofix).
The second system (from a different source) was brought to me with a BSOD 50; system repair fixed that, but otherwise diagnostics are as per the other system.
Having two systems with the same error implies to me a rogue Windows update?
Apart from a full system re-install. does anyone had success with a different solution?
