In testing, I can place all files in a known folder (C:\temp, for example) then use the command:
CODE
rundll32 setupapi,InstallHinfSection DefaultInstall 128 C:\temp\setup.inf
to install the program and all works well. I've tried this from guirunonce and it also works as long as I specify the full path to setup.inf.
I can make an addon cab file by putting all files in the svcpack folder and writing the ini file. I thought that would allow me to install as a hotfix, but no joy. Since I don't know where everything ends up, I don't know the path to setup.inf.
Is there a way to specify or predetermine where the files will be when the rundll32 command is executed?
Thanks,
Ray
