Is sapi5 present?
Could you give us more details on what’s sapi5 exactly?
Could you copy/paste links/URLs to related website or GitHub repositories?
It should be included as part of the OS according to Wikipedia, but the SDKs might need to be installed, probably via dotnet / nuget rather than choco.
Thanks for the precision!
Here’s what comes pre-installed on our Windows VMs: https://docs.travis-ci.com/user/reference/windows/#pre-installed-chocolatey-packages.
Based on this and what @jayvdb said, you should be able to install sapi5 yourself in your .travis.yml file.
Hope this helps!
