We have that, but this particular version escaped our testing:
In theory, we'd have to test against all released CTK version, every major.minor release.
Currently we're only testing against the latest major.minor releases.

It's a complex project to ensure full coverage at a reasonable cost (runner time).

This issue will be fixed with the next CTK release onwards. Windows Cupti will follow the same naming convention as linux
