Install latest version
I found a registry key in : [HKEY_CLASSES_ROOT\Installer\Products\C0D789EFB2038464299CC1DC40E36717]. Made a backup and removed it and I was able to install the last version. The key contains:

Install latest version
I have the exact same problem. The devolution.update.exe is nowhere to be found. The old version has completely been removed.
