When Installing DirectorWMIProvider_x64.msi on a XenApp 6.5 server, I was getting a error “Service ‘Director Windows Management Instrumentation Provider’ (DirectorWMIProviderHost.exe) failed to start. Verify that you have sufficient privileges to start system services.”
To fix this issue, install Microsoft .Net 4.5 and then DirectorWMIProvider_X64.msi.
