I am trying to install drivers with Inno setup and it looks like there are (at leas) two way to do this: add DPinst.Exe to the or run rundll against the .inf file.
I know there is two different version of DPinst for x86 and x64, are there different version depending on the OS (I need to support XP, Vista and 7)
Do I need admin permission for these methods?
Which method is recommended?
