Can't uninstall VMware player 5.0 from computer with Hyper-V
Modify the file
C:\ProgramData\VMware\VMware Player\Uninstaller\bootstrap.lua
or
C:\ProgramData\VMware\VMware Workstation\Uninstaller\bootstrap.lua
using a text editor and comment out line
CheckForMSHyperV()
with two dashes, so it will become
--CheckForMSHyperV()
Then save the file and rerun the uninstall and it will succeed.
