I've been trying to update this win7 machine (to sp1) and now I get this error. I'm in a catch22.
File search: windows_uCRT_DetectKeyExists, did not find path: C:\Windows\system32\api-ms-win-crt-runtime-l1-1-0.dll
So, the install can't find the dll. Because it can't find the dll, it won't install.
I get the feeling that a switch was changed during the builds (to not include some dlls) or Microsoft requires these now for compiling. Every version of FreeCAD has worked up to and including 18.16085. Anything newer than that will get this dll error (on a win7 without service packs). What this means is the current 18.xx release could have this issue.
You know I'm have fun.
