Double-Clicking associated file to open it triggers an error.



  • We just installed the 64-bit version and noticed that if we double click a file with a file extension which now opens with NPP, we see a dialog with the path and file name in it with this text: “There was a problem sending the command to the program”, but the file opens in NPP nonetheless. If we open NPP to a empty window then drag/drop the file into the window, all is normal. We renamed the Notepad++ folder under APPDATA but this didn’t address the trouble.

    How can we debug which command is the culprit so we can isolate it to try to fix it?

    Any help would be deeply appreciated.

    Many thanks,
    Dave

    Maybe procmon from sysinternals might help here.
    Download and run it, create a filter with notepad++.exe. Npp should not be active, double click the file and see what procmon reports in regards of starting npp.

    Cheers
