I'm using the 2.1rc5 windows installer with gui. Everything installs fine, except the tap-tun driver will not start.
The hardware device manager shows the following:
The device cannot start (Code 10)
You need to restart your computer before the changes you made to this device will take affect. However, I've rebooted several times and it continues to report the same error. I've checked the unsigned driver reject and also the RunOnce reg key.

Any ideas? Has anyone successfully used a recent version with Win2k?
Thanks


I've successfully installed 2.1-rc5 and 2.1-rc7 on Win2k as part of my testing of the latest TAP driver. But I would like to understand why it is failing for you.

So I've put together an OpenVPN installer that contains a debug-enabled build of the TAP driver.

Download:

http://openvpn.net/beta/openvpn-2.1_rc7-DBG-install.exe

Then download Debug View, a MS tool that will display driver debug messages:

http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx

Expand the zip file and run Dbgview.exe.

Select Computer -> Connect Local
Select Capture -> Capture Kernel

Now try installing OpenVPN. The TAP driver's debugging messages will be output to the DbgView window.

I'm attaching the DbgView log file of a successful install on Win2K.
