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 can't 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.
