This is (extremely) hacky implementation of some of the functions in the original api-ms-win-core-path-l1-1-0.dll which is needed during the installation of Windows SDK 10.0.14393.0 on Windows 7.

As explained here, WinSDK 10.0.14393 fails to install correctly on Windows 7 because mdmerge.exe depends on api-ms-win-core-path-l1-1-0.dll which AFAIK does not exist for Windows 7.

mdmerge.exe only imports PathCchCanonicalizeEx and PathCchRemoveFileSpec from api-ms-win-core-path-l1-1-0.dll

So this project implements these 2 functions so that mdmerge.exe is able to run.

Clone and build it yourself or download a statically precompiled release.

• Option 1:
  After building copy the x64 dll to system32 and the x86 dll to SysWOW64.
• Option 2:
  Copy to the install directory where mdmerge.exe resides.
  By default it is C:\Program Files (x86)\Windows Kits\10\bin\[x86|x64]

After the WinSDK setup installs successfully it might be safer to delete the hacky dlls from the system and hope that MS will fix this issue soon.
