RTR12, you have to install the latest version of SCARM, previous versions no longer work since SCARM is now a commercial product. There is a free version available, but, like AnyRail's trial version, its too limited to be of much value other that deciding if you want to purchase the full version. In your case it's probably not worth it since, like me, you already have RR-Track and know how to use it.
Also, I didn't mean to imply that RR-Track is hard. It's just that for what I use the inventory for, it's tedious when I want to compare prices from different sources. What I do is update the RR-Track data with MSRP prices to give me a ballpark cost projection. I then pull the data into Excel, but it takes quite a bit of editing to separate the data into their individual fields for use with formulas. SCARM lets me pull the data directly into their individual fields. To be fair, this is not something I do often, so it's just an observation. It's certainly not a reason to pick one program over the other.
