Error 1402 When Installing MS Virtual Server 2005

While installing Microsoft Virtual Server 2005 I encountered the following error:

Error 1402. Could not open key:
Verify that you have sufficient access to that key,
or contact your support personnel.

To fix the issue, I updated the parent folder HKLM\Software\Classes
permissions. When I looked at the permisions on this key it had only one entry: “Everyone” with Full Control. I added the SYSTEM account with Full Control and this fixed the error.

The specific steps I took to succesfully resolve this error are as follows:

  1. Launch the registry editor (Start > Run > Regedit);
  2. Navigate to HKLM\Software\Classes and right click Classes to get the context menu;
  3. Select Permissions… from the menu, you will see Permissions for Classes dialog box;
  4. Click Add and a Select Users or Groups dialog box will pop up;
  5. In the Enter the object names to select text box type SYSTEM;
  6. The Check Names button should become enabled – click it;
  7. SYSTEM should become underlined indicating it was recognized as valid;
  8. Click Ok and with SYSTEM highlighted be sure Full Control is checked;
  9. Click Ok, close the Registry Editor, and retry the Virtual Server installation again.

I hope this post has helped you.
