The Windows installer for 2.3 (both 32 and 64-bit versions) no longer installs the TAP-Win32 utility scripts by default (addtap.bat & deltapall.bat.) These scripts are required for end-users to manage TAP adapters, and specifically to install more than 1 adapter if use of multiple VPNs is required.
These scripts used to be installed under the .\bin\ path in <=2.2.2. In 2.3.0 this appears to have been logically split into a separate installer, tap-windows.exe, which has its own installation directory. By default, this installer does not install the optional "Utilities" feature, which causes these 2 batch files to be missing. As this tap-windows component installation is performed silently during OpenVPN installation, this option is never presented to the user. According to the NSIS source[1], this flag should be passed to the embedded tap-windows installer in recent versions of the build script. Looking at the way the program call is made using Process Explorer (PE) using the 2.3.0 release, the indicated line in the NSIS source doesn't match the 2.3.0 release package. Compare that line with what PE shows during installation: "C:\DOCUME~1\TestUser\LOCALS~1\Temp\tap-windows.exe" /S The source changes for the tap-windows project's own NSIS file[2] also appear to have been changed recently enough (similar timeline to the openvpn-build NSIS changes) that it may also need to be built from a recent source copy to get the correct macro (SelectByParameter) support required to support the /SELECT_UTILITIES feature flag. Unless I've missed something in the sources, it would appear the 2.3.0 build lacks a recent enough version of the openvpn.nsis script. The solution should be to re-package both installers with recent versions of the NSIS sources. Expected results are both TAP-Win32 utility batch files installed by default during a silent installation of tap-windows.
