I tried asking tech support at vmware.com...but they haven't got back to me and it's been six days now. I don't know how stupid my question is but here it is:

I start the vmware-install.pl script..and when I get to this question

What is the directory that contains the init directories (rc0.d/ to rc6.d/)?

It can't find my init directories.

I tried /etc/, /etc/rc.d, /etc/rc.d/rc2.d/ but still I cannot get past this question. I'm using Slack 10.0 and the VMware-workstation-4.5.2-8848.tar.gz package if that matters. Does anyone know what the directory is that I need

Thats because there isn't one dude. When will people on slackware that try and use vmware ever figure that out? Do this

cd /etc
mkdir init.d
for i in {0,1,2,3,4,5,6}; do mkdir rc$i.d; done

then run the vmware install and DON'T choose to configure it yet. Exit and run it manually like this

cd /usr/local/bin/
./vmware-config.pl --compile

and maybe copy the startup script to your /etc/rc.d directory if you want to start it on boot, else /etc/init.d/vmware start will get it going

There may be a little more to do after you do that, I suggest you do some gooooooooooooooooooooooooogling for the rest.

Thank you, Thank you, Thank you

the init.d directory was there, and after I used the for command, the vmware script took it, so thank you very much for the help.
