I am running XP mode under Windows 7, for testing / troubleshooting software.

I am trying to install a third party driver(unidrv printer), and I get stuck at

Setup failed to locate required files. 
It is required to provide the path of "I386" in Windows installation disc.
Click Browse to provide the appropriate path.

I have tried every location containing unidrv or other dlls on the VM (XP running "inside" virtual PC), as well as any I386 folders, but the installer was not happy.

My guess, it actually wants the installation disk... except, I don't have one !

How can I get an XP I386 folder from the installation disk, while running XP mode on Windows 7 ?

  • Copy I386 folder from CD to C:\I386 – STTR Mar 26 '15 at 20:28
  • @STTR he doesn't have the cd – miniBill Mar 26 '15 at 20:38
  • There is a c:/I386 folder, I pointed the installer to it but must not have the required info... – Thalia Mar 26 '15 at 20:41

    You can still download an XP SP3 ISO from Microsoft's Web Site. Link Here – N. Greene Sep 16 '15 at 13:47

    Unless you are actually using XPMode for an incompatible printer, why not install printer on Windows 7 and share to the XPMode virtual? – Shaun Vermaak Nov 10 '16 at 21:01

I worked with XP Mode a lot at my last job.

The only way to legitimately get the folder you need without buying another copy of Windows XP SP3 is to find another computer with a working Windows XP SP3 installation and copy the folder from there. This is if the printer is incompatible with Windows 7.

If your printer is compatible with Windows 7, then you can install it under Windows 7 and share it to the virtual machine under Windows XP Mode; this is much easier if you have the printer attached locally via USB or parallel port. Usually every resource on your Windows 7 computer is shared to XP Mode unless you elect not to in the Windows XP Mode configuration options.

  • Yes, yes yes. This is the correct approach if at all possible. May I ask what printer? – Señor CMasMas Mar 11 '19 at 21:27
