I am new to drivers and driver installers, so excuse me if this question is
too basic :)

We use the FTDI driver version 2.4.16 that supports both 32-bit and 64-bit
Windows. For installing this driver we are using DPInst.exe

According to this website:

http://msdn.microsoft.com/en-us/library/ms790308.aspx

DPInst version 2.1 supports later Windows and Vista versions. Does this mean
64-bit Windows/Vista also?

Or should I download one version for 32 bit and another for 64-bit
Windows/Vista, as said here:

http://www.microsoft.com/whdc/driver/install/32-64bit_install.mspx

I would appreciate any help on this.

Thanks.

Well, it's not the SAME driver. 32-bit and 64-bit require different driver
binaries.

You should use a 64-bit DPInst on a 64-bit system. I don't have actual
evidence that the 32-bit DPInst does not work, but I *do* know that
installing drivers with the 32-bit DevCon causes confusing results. It
appears to work, but the setup is not complete. Some parts of the install
process only work from a 64-bit process.

Both come with the WDK, so it's not a hardship.

Tim,
Thanks for responding. This answers my question fully.

Where can I download the 64-bit DPInst.exe from?

Thanks,

It should be provided with the WDK.

Thank you, Mike. I ran the Kitsetup program to set up WDK. I have three
directories - amd64, ia64 and x86, with a dpinst.exe in each.

Which one should I use for 64-bit Windows/Vista? I am guessing the
amd64/ia64. I tried searching the web for information on this, but found
nothing.

For some background I am a build/packaging engineer with no idea about
device drivers. So excuse the extremely basic questions.

Regards,
GK.

Really? The Server editions of Windows run on three different
architectures: x86 (32-bit), x64/AMD64/EM64, and ia64 (Itanium). The
client editions (like Vista) do not support Itanium, nor does anyone else,
really.

Unless you are working in a specialty environment, when you say "64-bit
Windows", you mean the amd64 choice.
