Failed to open key when Installing Dynamics NAV 2009

When installing Dynamics NAV 2009 one of my friend's rune into this problem:

Microsoft Dynamics NAV 2009 Build 27808
Error Report
RoleTailored client
Microsoft Dynamics NAV 2009 RoleTailored client
Fatal error during installation.

Could not open key: UNKNOWN\MSComDlg.CommonDialog.1\CLSID. Verify that you have sufficient access to that key, or contact your support personnel.

The problem here is that we have a mismatch of .NET. The simplest solution is to install latest version of a .NET and run the installer again.

.NET Framework 3.5 SP1
