  • 46 Ratings

  • Upgrading or uninstalling/reinstalling vSphere plug-in Clients fails.
  • Uninstalling VMware Update Manager Client 4.1 in Programs and Features fails.
  • You see the error:

    Error applying transforms. verify that the specified transform paths are valid


This issue occurs if an incorrect transforms path is specified in registry.


To resolve this issue, modify the transform path in the registry.

Note: In the registry, transforms are listed in a folder with an auto generated name. This name varies for different installations and must be identified manually. Because the folder names are 32 character generated strings, it can be difficult to identify the correct folder.
To modify the transforms value:
  1. Click Start > Run, type regedit, and click OK. The Registry Editor window opens.
  2. Click File > Export and back up the current registry.
  3. Browse the registry editor and locate:

    HKEY_CLASSES_ROOT\Installer\Products orHKEY_LOCAL_MACHINE\SOFTWARE\Classes\Installer\Products

    • In Update Manager Client 4.1, navigate to HKEY_CURRENT_USER\Software\Microsoft\Installer\Products\.
    • In Update Manager Client 5.0, navigate to HKEY_CURRENT_USER\Software\Microsoft\Installer\Products\Update Manager CLIENT GUID.

  4. Right-click the Products and click Find. The Find dialog box appears.
  5. In the Find what field, type VMware vSphere Client or VMware Update Manager Client.      
  6. In the Look at section, deselect Keys and Values and click Data.
  7. Click Find Next.
  8. Double-click Transforms.
  9. In the Edit String window, delete the information listed in the Value Data field.
  10. Click OK and close the Registry Editor window.  
  11. Use Add/Remove Programs to uninstall the old version of VMware vSphere Client.
