I found this in the community site of the latest release of VMware Workstation 7.1:

Many of our users are encountering issues with our Software Updates feature. We appreciate your patience and thank you for helping us iron out the bugs before we make the Workstation 7.1 release generally available.

We will be posting a second Release Candidate shortly to ensure that the issues that have been reported have been fixed.

In the meantime, if you are running Windows Vista or above on a non-English host operating system, and attempting to update your Beta fails after granting UAC access please try replacing vmUpdateLauncher.exe. A new version of this file and more details can be found here:

Non-English users: Having problems updating Tools or to RC? Fix within.

If you are running Windows Vista or above on a non-English host operating system, and attempting to update Workstation fails after granting UAC access, please try replacing vmUpdateLauncher.exe in C:\Program Files\VMware\VMware Workstation\ with the attached vmUpdateLauncher.exe.

The problem affects beta and RC and will not be properly released until later.

You can tell if you have the problem if the update does not work by checking Task Manager. If vmUpdateLauncher.exe is eating 100% of your CPU, you are experiencing this problem. If not, it may be something else.

Thank you for trying out the beta!
