Hi, Please could someone guide me in the right direction. I am trying to perform a silent install of directx_mar2008_redist.exe via the command line. I can make it extract into a temp directory but not start the install after it has been extracted? This is my command line to extract: directx_mar2008_redist.exe /Q /C /T:C:\TempFiles\directx I do not know how to start the install. I don't want to do this using two commands, I would prefer the single command to extract AND install silent. I don't want to extract the contents of directx_mar2008_redist.exe because I want to just supply a single file to use as part of a silent install for a application. Thanks in advanced Paul
