I just found the following on the web. Although I realize that these steps are for an older version of VMWare Workstation), it might be of some use. Note: I haven't tried this myself (I am trying to get version 8.00 of Workstation working on Slackware 13.37_x64
When I try to install VMware Workstation 3.2 on my Linux host, I get an error
message that says a VMware product is already installed. I cannot find any such
installation. How do I remove previous installations manually?
To manually uninstall VMware Workstation 3.x, follow the steps below.
Note: The directories listed in steps 5 and 6 are correct for Red Hat Linux 6.x. If you
are running a different distribution, check for the correct init path by using this
ls -al /etc/rc.d/rc*.d/*vmware
Substitute the correct path in steps 5 and 6.
1. Log in as root.
2. cd /lib/modules/misc
3. mv vm* /tmp (assuming that you have a /tmp directory)
4. Run rmmod for each module:
5. rm /etc/rc.d/init.d/rc5.d/*vmware
6. rm /etc/rc.d/init.d/rc6.d/*vmware
7. rm -rf /etc/vmware
8. rm /usr/bin/vmware*
9. rm /usr/bin/vmnet*
If you installed VMware Workstation from the RPM package, you must also take the
following steps to remove VMware from your RPM database.
rpm -qa |grep VMware
This returns <packagename>.
rpm --erase --nodeps <packagename>
