I just ran into the same issue with Windows XP SP3 and the View 5.0 Agent. A search led me to your post, and the VMware Tools repair worked for me too. Thanks for the tip!
I'm seeing the same thing with the View Agent 5 update 1 (VMware-viewagent-5.0.1-640055) on XP with SP3. The repair of tools fixes the out of date message but it's a little disconcerting since the vmware documentation says the agent should always be installed last.
Has anyone found a fix or VMware released a fix for this issue yet? Repairing tools doesn't seem to resolve the issue for me.
Any fix on for this. I had to reinstall so many times. Until I just did a reinstall of tools. ??
