Fixing “Windows Installer Coordinator” loop

2013-08-02Vaidotas

Sometimes when you install software, you got stuck at window which says “Windows Installer Coordinator”
There is easy fix for this, which involves changing setting of Group Policy.
 To disable this group policy you need to perform these steps:
1 ) Log on to the system with a User that has Administrative Privileges
2 ) Open the Windows Control Panel
3 ) Perform a search for Group Policy
4 ) The search results should display a link to the “Local Group Policy Editor”
5 ) Once inside the editor, go to:

1. Computer Configuration
2. Administrative Templates
3. Windows Components
4. Remote Desktop Services
5. Remote Desktop Session Host
6. Application Compatibility

6 ) In the right pane, right click on ‘Turn off Windows Installer RDS Compatibility” and select Edit from the drop down menu
7 ) Select the Radio Button labeled ‘Enable’
8 ) Click OK
