TAP install Windows XP-SP3 fails

martinbln

Hi there,

I'm trying to install OpenVPN Client on a WinXP Machine with SP3, 32 bit.

It always fails when it comes to install the TAP Driver: "An error occurred installing the TAP device driver".
Log Entry:
"tapinstall hwids returned: 0
TAP UPDATE
Updating drivers for tap0901 from C:\Programme\OpenVPN\driver\OemWin2k.inf.
UpdateDriverForPlugAndPlayDevices failed, GetLastError=2
tapinstall.exe failed.
tapinstall update returned: 2
tapinstall cumulative status: 2"

The TAP Device shows up in the in the device manager with an exclamation mark (code 28, driver not installed).

Trying to add the TAP via "add new hardware" manually doesn't work and ends up with "the system can't find any file" or something.

The Registry has the needed RunOnce entry in HKEYLocalMach/Software/Microsoft/Windows.
I tried different Open VPN versions: 2.0.9, 2.1.3, 2.2 beta3. Always the same error.
I tried cleaning the Registry as well with TuneUp Utilities and Regclean.

It's just impossible to install the TAP driver correctly.
Any ideas?

Thanks in advance!

maybe try removing and installing manually if you can... see this section of the link below:

thanks for your answer, krzee!
unfortunately, a manual install doesn't work as well: Update Driver for PlugandPlay Devices failed, GetLastError=2. tapinstall failed.

Any other ideas, anyone?

This sounds more like a core windows issue, than an OpenVPN specific issue. If all those version are, indeed, failing, there seems to be something corrupt in the registry that's preventing the device from being properly installed.

Not that I'm suggesting you go elsewhere, but you may have better luck in a Windows-specific forum.

Sorry guys for necroing, but I did it, because google comes up with this thread if someone searches for OpenVPN in combination with WIndows XP and the TAP driver.

What does in fact help to solve the problem, is the forked OpenVPN v2.5.4 for Windows XP. We recompiled the driver, added support for 1 GBit/s network connections, which has be capped to 10 MBit/s before and removed problems with the cat file of the original TAP driver for Windows XP.
