 but am optimistic.

 I think this works now without the spec hack due to switching to ucrt
 which should be available on all supported platforms. It seems both 64bit
 and 32bit bundles are working both on Windows 7 and Windows 10 systems and
 I tried the new 32bit version on my Windows 7 box where I previously had
 the problem at hand. However, it works there as well now. Thus, I'd say we
 are good here. I'll close the respective bugs on our side once the patch
 for this bug lands.
