The installation of XenDesktop 7 fails with the following error:
Installation of MSI File 'ADIdentity_PowerShellSnapin_x65.msi' failed with code 'InstallFailure' (1603).
Install .Net 3.5 SP1 or Later
In the installation log, you can see that msiexec was started and passed the path to the MSI file in the error message. The installation failed, but it doesn't really say why.
The log shows that verbose logging was enabled, but MSI logs aren't fun to parse. Instead, I ran the MSI directly. It spit out an error telling me that .Net 3.51 SP1 or higher needs to be installed.
Install .net 3.5 from a command line. Adjust it to the correct DVD drive, or SXS folder and run the following command as an Administrator.
DISM /online /enable-feature /all /featurename:NetFX3 /source:D:\Sources\sxs
