     1= Installing an uninstalling the TAP-drivers =
     2
     3Occasionally you may have to try out different versions of the Windows TAP-driver. This can be done with ''<openvpn-install-dir\bin\tapinstall.exe''. This tool is actually renamed [http://support.microsoft.com/kb/311272 Devcon.exe].
     4
     5It's fairly straighforward to use ''tapinstall.exe'' from a command-prompt. The <id> is an identifier which ''tapinstall.exe'' uses to detect the correct driver. In case of OpenVPN 2.2* it's ''tap0901''. This may be different in older/newer versions. To view information about an installer driver use
     6
     7{{{
     8$ tapinstall.exe hwids <id>
     9}}}
     10
     11To uninstall a driver use:
     12
     13{{{
     14$ tapinstall.exe remove tap0901
     15}}}
     16
     17To install a new TAP-driver use
     18
     19{{{
     20$ tapinstall.exe install <something.inf> <id>
     21}}}
     22
     23It's also possible to [wiki:BuildingOnWindows#ExtractingsignedTAP-driversfromanOpenVPNinstaller extract TAP-drivers from OpenVPN installer] without installing OpenVPN.
     24
     25= Extracting TAP-drivers from OpenVPN installers =
     26
     27If you need to run OpenVPN on Windows Vista/7 64-bit you have to use signed TAP drivers. Unless you sign them yourself, you need to do two extra steps:
     28
     29 * Extract the TAP-drivers (*.cat, *.sys, *.inf) and ''tapinstall.exe'' from an official OpenVPN installer using [http://www.7-zip.org/ 7-zip]. The 64-bit versions are larger in size.
     30 * Place 32-bit signed TAP drivers and corresponding ''tapinstall.exe'' to ''<openvpn-build-root>\tap-prebuilt\i386''
     31 * Place 64-bit versions to ''<openvpn-build-root>\tap-prebuilt\amd64''
