Description

Cause

  1. Connect to the computer as an Administrator.
  2. Open the Windows Start menu, type gpedit.msc, and press Enter.
  3. In the left pane, select Computer Configuration.
  4. In the right pane, open Administrative Templates.
  5. Open Windows Components, then select Remote Desktop Services.
  6. Open Remote Desktop Session Host, then select Application Compatibility.
  7. Select Windows Installer RDS Compatibility.
  8. Select Enabled, then click Apply, and OK.
