Hello,
I think you need to be more specific.
For VMware on Windows 7 x64 there was a problem downloading tools packages from VMware into VMware Player and performing an automatic Install of VMware Tools in a guest operating system using the VMware menus.
I had that problem.
And suggested a fix for it here:

Depending on the specifics of your problem the solution may or may not be of use to you.
Hope it helps.
