Hello, I have encountered the same error a few days ago, have you run the ".\vcpkg integrate install" before installing your first package? If it is the case, start a fresh clone of vcpkg, install your package(s), and then integrate install (further package installations would not trigger this error).

[herbthompson]

Thanks for the suggestion. I tried that but got the same result.

I ran into the same problem. Digging deeper into the logs it seems the linking of zlib fails.

Is this the same for you herbthompson?

[derkestrel]

ucrtd.lib is supplied by the windows 10 dev kit and is for my system in C:\Program Files (x86)Windows Kits\10\Lib\10.0.14393.0\ucrt[x64|x86]\'ucrtd.lib, both of which I added to my path variable for testing. Still fails.

[derkestrel]

The last update fixed this problem for me.

Hope it is the same for you @herbthompson ?

[herbthompson]

Thanks for the info @derkestrel . The new version works for me too.

Should be fixed in the latest versions. Please let us know if you continue to have issues!
