Hi, I recently tried upgrading to the latest Windows Insider build (16215) in the Parallels VM I use for Windows Insider testing. On both attempts (one with 3D acceleration enabled and one without) both upgrades to 16215 (from the previous insider build) failed, and Windows rolled back the installation. So, I tried uninstalling Parallel Tools for my next attempt, and this time the 16215 update was installed correctly. I was then able to install Tools inside the new build (though I got a scripting error when doing this). So, I'm just wondering, considering there were a lot of changes in 16215, whether a new compatible version of Parallel Tools needs to be released? And just to bring this problem & workaround to others attention. Thanks.
