OpenVPN Support Forum

Hi all,

I have recently configured a pfsense server for VPN, and am testing out the OpenVPN
client on a few users. I have installed OpenVPN and it is up and running like a dream on all the users PC's its been tried on, OS's being windows XP, and windows 7.

However today when installing it on a users laptop, on XP sp3, it will not install the TAP-Win32 device driver.
During installation an error box appears;

"error occurred installing the TAP-Win32 device driver"

The login account does have administrative rights, (right clicking the install file and selecting run-as the selected user has admin rights), and I have tried the previous version rc19, still has same problem (read on another forum this solved the problem for someone)

Any suggestions ? Much appreciated.

if your previous version is rc19... you are using 2.1.1 right?

Sorry, should have mentioned ive tried openvpn-2.0.9 giu, and am about to try 2.1 beta7, but am expecting that not to work either.

Have only tried the gui version, but im assuming that the problem is not with the type of installer, but to do with the TAP-Win32 driver installation.. ?

I managed to get it installed, what I did was (not sure which one solved the problem tbh):

* uninstall a load of junk on the users computer (blackberry applications, norton internet security.. which was expired anyway)
* Start > All Programs > OpenVPN > Utilities > Delete ALL TAP-32 virtual Ethernet adapters
* uninstalled openvpn gui
* create a new acccount on the pc, with admin rights.
* logout, then login wiht new account
* install openvpn gui

This worked, it created the TAP-Win32 adaptor. I then logged in with the user account, and the application and adaptor were there, and working.

I'm not sure why you're using 2.0.9 or 2.1rc7, as 2.1.1 was released a little over a month ago. The Windows installer includes the GUI now.

I second ecrist.. update man come on. No need to run dated software.
