Many laptops now run VISTA 64, when do you plan to support the 64-Bit version, since you now provide support 32 Bit VISTA?
Which product in particular are you requesting support for?
I notice you already asked this question in the easyC technical support forum:

I assure you that all VEX Motion & Structural components are 100% Vista 64 compatible. 
Yes, I did ask it already but they say the problem is with the IFI Orange Programming cable. I am trying to use Easy C 2.0 on my HP laptop running VISTA-64 Bit Home Enterprise Edition. Do you have new drivers for the IFI Orange USB Programming Cable?
