    9 In addition, a tool called ''<openvpn-install-dir>\bin\tapinstall.exe'' is provided. It can be used (among other things) to install and unistall TAP-drivers manually. This tool is actually a simply a renamed [http://support.microsoft.com/kb/311272 Devcon.exe].
     9If 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 extract drivers from an existing OpenVPN installer. See below for instructions.

     11OpenVPN installers come bundled with a command-line tool called ''<tap-windows-install-dir>\bin\devcon.exe'' for managing the TAP-driver. Two wrapper scripts, ''addtap.bat'' and ''deltapall.bat'' are also available in the same directory. For details on ''devcon.exe'' usage look at [http://support.microsoft.com/kb/311272 Microsoft's Devcon.exe documentation].

    15 Occasionally you may need play with different TAP-driver versions. In this case you can use ''tapinstall.exe'' from the Windows command-prompt. Below are some common commands; <id> refers to the driver identifier which is ''tap0901'' for OpenVPN 2.2*. This identified may be different in older/newer versions.

    46 Recently tried "openvpn-install-2.3_rc2-I001-x86_64" ("release candidate" for x64 platforms); OpenVPN installer do NOT created ''<openvpn-install-dir>\bin\tapinstall.exe''; but it created additional folder in "Program Files" - ''Program Files\TAP-Windows''; if NOT - unpack the installer package with {7-zip}, go to unpacked "$temp" folder and run ''tap-windows.exe'' (unfortunately, no any shortcuts are created in your system to any of the tools/files in this folder).
    47 To add another virtual TAP-adapter - go to "\Program Files\TAP-Windows\bin" and run ("as administrator" !!!) the file named ''addtap.bat''
