There is a way to install it silently as I do in my installs. I can't tell you at the moment as I am currently at work. Will update you with the way to do it when I get home unless someone beats me to it.
EDIT:
Ok here is what I use:
CODE
ECHO Installing VMware Workstation v4.0.2 Build 5592
ECHO Please Wait...
start /Wait U:\Applications\VMware\VMware.exe /s /v"/qn REBOOT=Suppress"
ECHO.
ECHO Finished
ECHO.
and to regiser it I use:
CODE
ECHO Registering VMware Workstation v4.0.2 Build 5592
ECHO Please Wait...
REGEDIT /S U:\Applications\VMware\VMware.reg
ECHO.
ECHO Finished
ECHO.
The registery info after you install it and register it is in this location at:
CODE
[HKEY_LOCAL_MACHINE\SOFTWARE\VMware, Inc.\VMware Workstation\License.ws.4.0]
No reboots and works perfect. Hope this helps you out.
