TroubleShooting guide for .NET Framework 3.5
While installing PMA, we need to make sure that all pre-requisites have been installed on our machine.
During Testing for Flavor UCM To FS on Windows Server 2012 server, we had observed that it didn't allow us to install the .Net Framework 3.5 . An error message pops up saying choose an alternate path & Installation has failed.
Upon investigation, this behavior is caused by system administrator who configures the computer to use Windows Server Update Services(WSUS) instead of the Microsoft Windows Update server for servicing. Server sometimes is not configured to use Windows update( Common for managed servers).
Below mentioned steps can be used to overcome this issue :-
1)Start the Local Group Policy Editor or Group Policy Management console.
2)Expand computer configuration, under that expand administrative templates and then select system.
3)Open the specify settings for optional component installation and component repair group policy setting and then select Enabled.
4)Select the Contact Windows Update directly to download repair content instead of Windows server update services (WSUS)check box. Make sure Windows Update Service is set to Manual or Automatic to apply this fix.
