Having issues with select source

[ScannerProgrammer]

I have two separate scanning programs on the same machine.

When I hit Select Source in one program 7 different scanners show up.

When I hit Select in the other program only WIA scanner shows up. Why is this WIA the only one to show in the program?

WIA and TWAIN are two different protocols.
Scanners can support as many different protocols as the manufactures want.
Applications can choose to support TWAIN, WIA, or both.

Microsoft includes a method in Windows to expose WIA drivers though TWAIN. For scanners that have released both WIA and TWAIN drivers those scanners will be listed twice. These WIA drivers listed in the TWAIN select source dialog, only support a subset of the functionality of TWAIN.

To remove the WIA drivers from the TWAIN Select Source dialog, rename the file C:Windowstwain_32wiatwain.ds
