Question:

How do I run an install in Windows 95 from an *.INF file? How can I install a .inf file from the command line?

Answer:

The normal method to install a .inf file is to right click on it and select Install from the context menu however it is also possible to install from the command line. The syntax is:

C:\> rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 .\.inf 

Another user reports:

I can tell you the syntax we are using for NT, I assume it will work with 95 but I can't confirm.

runshell("c:\winnt\system32\rundll32.exe","setupapi,InstallHinfSectionDefaultInstall 128 filename.ext", "c:\winnt\system32", @hidden, @WAIT)

Example to install the DosHere PowerToy:

Str1 = 'c:\temp\doshere.inf'  ; full path to INF file
RunWait( 'rundll32', StrCat( 'syssetup,SetupInfObjectInstallAction DefaultInstall 128 ', Str1 ) )
