Vmware not compatible with vistas as host

hello,

I tried 5 or more times to make Vmware Workstation 5.5.3 or even the Vmplayer working on my Vista RTM US.

I always take a blue screen on the host caused by vmx64.sys or something like this.

I give it up until an official version supporting Vista.

I could not manage to install the Virtual Center client either.
The simple remote console is working anyway.
