Wrong message "VMware Tools can be updated" for VM inside ESXi 4.1

[Horinius]

Those VMware Tools in my guest OS keep on showing “VMware Tools can be updated” and the yellow exclamation.

Host OS is ESXi 4.1.0 build 348481

VMware Tools version is 8.4.8 build 491717

It’s not about the files with .001 extension as stated in the following article

http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=200138...

I have checked and there is no file with that extension.

I think the VMware Tools is unable to read or compare the correct numbers.  Or is there any other reason?

Answering my own post:

The answer, actually the procedure, is inside this article:

https://communities.vmware.com/docs/DOC-31365

For some reason, VMware Tools is not installed correctly (eg files from previous versions are left inside the hard drive).  So need to do manual cleaning before reinstalling the tools.
