You can solve this by being in the visual studio development command prompt when you install it, but really we should have wheels uploaded. @twizmwazin, did you forget to do the windows wheels for the january 7 release?

[twizmwazin]

I don't believe we ever got around to doing windows wheels from the last release, just linux ones. When I have time, I think it would be a good idea to integrate this in some way with azure pipelines so that we can build wheels for all the platforms with one button click.

[rhelmot]

Yes, that would be nice, but can we fix the current release?

[twizmwazin]

I won't have time until next week, I may be able to see if someone else with an environment already set up can.

I also have this problem in win10. and i solve it just now. i think you neednt install VS, just install visualcppbuildtools_full.exe and use VC++ command prompt to "pip install pyvex".
