I believe I experienced this issue several months ago; it was a bit tedious in how I rectified it. I searched all over (Google) but couldn't find anything specific. So this is what I did....
Do you have any other VMware products installed?...like VI or vSphere Client?...any plug-ins for VI/vSphere? Pretty much any VMware product you have...remove from Add/Remove pgms. Then, in the registry at:
HKLM->SOFTWARE->VMware, Inc....rename VMware, Inc. to VMware, Inc.OLD. (it shouldn't mess with anything but I do advise, when making any registry change, to back up this area BEFORE renaming it; to do so, just right-click on the VMware, Inc. heading/key and select to Export it...you can do so to your desktop and name it as you want to).
Now, go through your install of Workstation...I believe it will work. Once complete, you will then have to reinstall your other VMware products/apps/plug-ins.
