Inno设置：用rundll32或dpinst安装驱动程序？

Question

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?

Answer 1

You use the same DPInst version for all versions of the operating systems; the only distinction is 32-bit vs. 64-bit. The WDK comes with both 32-bit and 64-bit versions.

Personally, here's what I do (on InnoSetup):

[Files]
...
Source: ...\dpinst32.exe; DestDir: {#DpInstPath}; DestName: dpinst.exe; Check: not IsWin64; Flags: ignoreversion
Source: ...\dpinst64.exe; DestDir: {#DpInstPath}; DestName: dpinst.exe; Check: IsWin64; Flags: ignoreversion

Using run32dll setupapi.dll,InstallHinfSection ... is outdated and generally not recommended unless you have some very specific needs.
