WIA issues on windows 7, works perfect on 8

    Question

  • I have 2 problems,

    1) a machine I need to use for debugging will not show the scanners plugged into it in my dialog but will in windows scan and fax, the same scanners show in windows 8 and other win 7 machines.

    2) i'm trying to debug why the app crashes when the transfer is called on windows 7 only.

    Scan And Fax for windows shows my 2 scanners on windows 7 but using a custom app that implements native WIA in c++ it does not show the scanners in the select device dialog.

    This app works fine on windows 8 and some other windows 7 machines although it crashes when doing the transfer with the below crash info.

  • 2) is fixed by removing IWiaAppErrorHandler from my callback class. some reason sti.dll was getting access exception after the return of this instance from QueryInterface

    1) still happens but the device is there if I enumerate it and not use SelectDeviceDlg
