Could this be a code signing issue?

Or maybe MSVC built binaries needing more recent libraries?

Copying in @stipa and @selvanair, they understand windows...

2.5.5 works for me on Windows 7 (6.1 build 7601 SP1).

What is the output of "sc query OpenVPNServiceInteractive"? Anything interesting in event log?

I did clean install in 32bit, same result..
In first view nothing interesting in Event log, besides starting service error...
but in Eventlog security section there is something that might be related:

Anyways Fresh install of windows7 64bit was a little more chatty and it seems that problem is with with driver signing:

Is there any additional logging/debugging required from us?

@mattock: wasn't there some shenannigans with SHA-something signatures and Windows7? Like, needing to install a hotfix or such? I forgot the details...

[Selva Nair]

The service is not starting because tap driver failed to install, it could be missing SHA-2 support. But how come only 2.5.4+ are affected?

The hotfix for Windows 7 is kb4474419:
Deatils here: ​sha-2 support
Download link: ​kb4474419 64bit
Or ​kb4474419 32bit
