For those of you getting into VMWare, you might try and install the VI client on your machine. If you have a 64 bit OS such as XP or Vista 64, you will get an error message saying you can’t install it because it’s only supported in a 32 bit environment.
The long and the short of it is that VMWare has made some changes to the client that might cause issues in 64 bit so the developers blocked 64 bit installations intentionally. You can still get around this however.
My personal favourite way is to just install a VM on your computer with a 32 bit OS and then run the client out of there. There are other things you can do is well and I suggest you read this link found here about the situation.
