    Hi - New Forum user here.
    I have been using DPP4 (4.16.0) for a little while. Used it this morning ok. This afternoon, it didn't appear to start, but hitting Alt-Tab it shows a small window. YOu can't select Maximise.
    I have un-installed and re-installed - no change. If I select a file, right click and "Open With" DPP4 same thing happens.
    Running Windows 11 21H2 Build 22000.556

    Any suggestions? I am guessing its something straight forward - but not sure what else to try.
    Mark

    Solved: Finished up locating the DPP4 AppData Directory (\Users\Username\AppData\Local\Canon_INC\DPP4...\4.16.00
    In this directory was a user.config file. I deleted it and restarted DPP4 - it came up as it normally should.
