Make sure the license key is saved to file with a '.reg' extension. The next time you run 'vmware' the license errors should not appear. To verify that the license key was installed properly you can check the registry, but be VERY careful to not modify the contents of the registry as it can adversely affect the operation of your system. If the License folder does not exist, the license has not been installed properly. Yes, follow the steps documented in this note .
Workstation uses unique build numbers for each product release.
As with the Workstation products, VMware Tools also have a build number. This isn't all that surprising, we've tested a fair number of operating systems and have a pretty good idea of which work and which don't. If you really want, you can file an incident report and include the log, core, and a description of the failure mode, but there's most likely a reason that operating system is not currently supported. This problem is most likely caused by your host computer just logging out after the install instead of correctly rebooting. Try rebooting your computer manually and see if this problem goes away.
