Weird error installing drivers for USB cable

[RokrZ6]

Hi guys, was going mad trying to make MPT4updated to see my Z6 on my XP machine, then found out your drivers (probably same drivers from MotoDev site).
Fact is this: launching the .exe file i get this:

The folder path "Program Files' contains an invalid caracher.

Clicking the only button available, OK, i get this:

The installer was interrupted before Motorola Driver Installation could install drivers. You need to restart installer again.

oO!!! Damn, ofc the 64 bit version not working too...
If i cant get my driver installed no way i can get any connection...

Any help appreciate.
