Hello, I am trying to run an INF from a batch file in order to update the
latest client. I would like to install Patchkit C for 4.9.1 sp2.

I have read previous posts and have tried the following commands

C:\>RUNDLL32.EXE SETUPAPI.DLL,InstallHinfSection DefaultInstall 132
z::\path\_491psp2_pkc.inf

C:\>RUNDLL32.EXE SETUPAPI.DLL,InstallHinfSection DefaultInstall 132
\\server\vol\path\_491psp2_pkc.inf

The command window then says, Access Denied and the inf file opens as a
text document.

I have also seen the error, Installation Failed.

Any ideas?
