I suspect that my Phidget21 library is 32 bit, and my new PC is 64 bit.
I did not see different versions ( x86 or x64 ) in the list of library downloads, can you provide a URL to Phidget21- 64 bit download?

My robot currently contains a Win 7, 32 bit PC and two 8/8/8 (PN. 1019) I/O boards. I'm using the Phidgets libraries 2.1, my application code is written in Visual Basic.NET. I am trying to upgrade the PC to a beefier Windows 11, 64 bit unit. I tried using Phidgets Libraries 2.2, but the method names...
