Update ePO 5.9.0 to 5.9.1 fails : Error applying transforms

[Recky]

Hi,

To upgrade from ePO 5.3, I have installed a fresh ePO 5.9.0 installation on a new Windows 2016 server and started migrating clients, policies, tasks etc. Everything works fine.

However, how do I go about updating to ePO 5.9.1? I downloaded the EPO591L zip and ran the setup, but the windows installer immediately fails with an error : "Error applying transforms. Verify that the specified transform paths are valid."

Am I using the wrong method to update ePO to 5.9.1?

Nevermind, fixed it by deleting the "transforms" value under the HKEY_LOCAL_MACHINE\Software\Classes\Installer\Products\A3ECAAD6A26D7B34DA0164F35E24FD01 registry key

Good deal, that is what I would have advised also.
