VB.NET application, first user on Windows 7 64-bit is having trouble getting up and running. Phidgets driver appears to install OK, but running the app gets the following: "Unable to install or run the application. The application requires that assembly Phidget21.NET Version 2.1.6.284 be installed in the Global Assembly Cache (GAC) first."

I am not hardware-savvy... are there compatibility issues with Win7 64, a special process to install the Phidgets package, something my app needs to do but isn't? Any help would be greatly appreciated!

Thanks,
Paul

Any thoughts? Can anyone cofirm or deny that the Phidgets 21 Installer run under Win7 64-bit in fact installs in the GAC?

Anyone at all?

I believe that the windows installer, irregardless of architecture, installs the .NET libraries in the GAC.

What I think that error is really saying though however is that it is looking for the specific version of the Phidget21.NET libraries (2.1.6.284) in the GAC. Your installer is most likely installing a different version of the Phidget21.NET libraries in the GAC.

The problem here is that the VisualBasic.NET application you are using was developed such that the reference to the Phidget21.NET libraries was to look for a specific version, which can be modified to be version independent in the reference properties.

It actually doesn't matter if the version matches exactly - but the fist three digits need to match. Your software is looking for 2.1.6.x and the current version is 2.1.7.x. You need to either install an older version, or update your reference to phidget21.net and recompile your app.
