If when trying to run VMware after upgrading or installing it gives:
Before you can run VMware, several modules must be compiled and loaded into the running kernel.
Kernel Headers 3.8.0-19-generic
Kernel headers for version 3.8.0-19-generic were not found. If you have installed them in a non-default path you can specify the path below.
or something similar, Simply run:
# Should work for any kernel header sudo apt-get install build-essential linux-headers-$(uname -r)
Then rerun vmware (for VMware Workstation) or vmplayer (for VMware Player)
