I've been running a 1500 on my laptop (WinXP,SP3) and a 5000A on my desktop (Win7 Ultimate, 64-bit), both using PowerSDR 2.0.8. I decided to try and get them both running on the desktop computer. I followed the instructions in KnowledgeBase Article 50469 and created a 2nd shortcut on the desktop for the 1500. I modified the Target Field in the shortcut properties as follows:

"C:\Program Files (x86)\FlexRadio Systems\PowerSDR v2.0.8\PowerSDR.exe" -datapath:"%appdata%\FlexRadio Systems\PowerSDR v2.0.8\FLEX-1500"
**
When I started it, it ran the one-time optimization. The Radio Model dialog box was next. It was already checked for the 1500, so I hit next. And finally I hit Finish. Next comes a Driver Error dialog box "Error opening radio driver." I hit ok and PowerSDR starts up. From the Setup Menu, I select Windows WASAPI and Flex-1500 for the Input/Output. Hit Apply and then OK, but now the Start button doesn't seem to work. So I closed PowerSDR and reopened it. Next there is a dialog box with the following:

"Could not load file or assembly 'wdapi_dotnet1011, Version=10.1.10, Culture=neutral, PublicKeyToken=null" or one of its dependencies. The system cannot find the file specified. . . . "

I checked to see if the dll exists and found it in the following locations:

Any ideas how to get the 1500 to co-exist with the 5000A on my desktop computer? I plan to run both radios simutaneously. BTW, when I first plugged the 1500 into my computer, it found the drivers ok and indicated that I was good to go. Also, during the above exercise, the 5000A was powered off.
