Thought I'd share this as its taken me a while to figure out why an Update Manager install on top of a working vCenter 4.0 kept failing with the above error. This was on x64 but I suspect it will be the same on x86.
Although you can generate an MSI log from the update manager installer executable (it doesn't like you running the msi directly), this doesn't help as it just gives the error message without any detail or context. The key log file was vminst.log which is found in %TEMP% for the user running the installer. In there it gives the command line given to the vciInstallUtils.exe program (which is run by a custom action) which when run manually shows me that I've been a muppet and given the account that I specified for VC access in the installer the wrong permissions in VC. A quick change of the permissions, rerun the installer and it's working.
It's also interesting because it shows why you need to have no special characters, such as spaces or quote marks, in the password you specify since it is passed unquoted, via the -P option, to the vciInstallUtils.exe program so spaces will be interpreted as a separate command line option.

I hope this saves someone else the few hours it has taken me to get to the bottom of it.
