I've started to upgrade our test environment from 5.2 to 5.3 and the composer upgrade failed removing the old composer in the process.
I found this on the vmmsi.log
VIEINSTUTIL: Begin install
VIEINSTUTIL: CustomActionData = vstor2-ufa;Vstor2 UFA Virtual Storage Driver;C:\Program Files (x86)\Common Files\VMware\VMware Universal File Access\vstor2-ufa.sys;2;1

VIEINSTUTIL: Finish install
CustomAction InstallVstor2Driver.5ACA97E0_7C64_4970_A763_840E81DAAF0B returned actual error code 1603 (note this may not be 100% accurate if translation happened inside sandbox)
Action ended 9:08:51: InstallFinalize. Return value 3.
i found this KB article VMware KB: Upgrading from View Composer 3.0 to View Composer 5.2 fails intermittently But i've tried multiple times and still fails...
Composer is Co-hosted with vcenter server.
Anyone else seen this?
