I have an MSP (Microsoft Patch) file, which installs some updates. But when I run it, it shows an error message, which says, that it cant read the file from C:\Windows\Installer\SomeFileName.msi But this file is there, I checked that out. I tried to run it with Admin rights, from powered cmd, from PowerShell, no luck. How I can fix that situation? Help please.

Try downloading the msp from its source again. It might have been corrupted during download or copying. – Robert Kerr May 13 '12 at 2:28
That doesn't help. Sorry. I downloaded it several times, from several sources. Even its previous patch also in MSP format had the same error message. – Matubo May 13 '12 at 3:36
See if this Microsoft Fixit can – Moab May 13 '12 at 13:06

I've found the cause of my problem. As it seems, these programs, which use MSPs should be installed in their default folder, such as "C:\Program Files...". Then these MSP patches work fine.
