• Version: master
• Platform: Windows 10 64-bit
• Subsystem: build

When I run vcbuild or vcbuild vs2017, it results in the following output:

Failed to create vc project files.

I have a "v10.0" key under HKLM\SOFTWARE\WOW6432Node\Microsoft\Microsoft SDKs\Windows (but not under HKLM\SOFTWARE\Microsoft\Microsoft SDKs\Windows). The ProductVersion value under it has data "10.0.15063" even though I don't have that specific Windows 10 SDK version installed. I might have previously installed and removed it though. Consequently, I don't have a "10.0.15063" directory under C:\Program Files (x86)\Windows Kits\10\Include, so this line returns an empty list.

Get the same thing. Have no idea how to fix it.

[seishun]

You can fix it locally by removing the offending registry key.
