My laptop died and I'm purchasing a new one. Does RealBand run with Windows 7 - 64 bit operating system? Thanks!

Yes. Many of us are using RB (as well as BIAB) just fine with Windows 7 64-bit. There are some folks who have had some problems, but most are working fine. Often the problems are traced to driver issues (especially if the device doesn't have a Win7 driver, or the driver is pretty new and may still have a few bugs).

VSC DX will not work in 64 bit OS, otherwise it works great.
Thought I would mention the 64 bit issue with VSC in case you counted on that part.
