Google Gemini - Advanced Diary 9.0 Access Violation at address 75D947DC

I installed Advanced Diary 9.0 on an Ubuntu Linux 26.04 system using Wine, but when I start it I see an error window with the message ""Access violation at address 75D947DC in module 'qcap.dll'. Read of address 5F505353." How do I address that problem?

Google Gemini Response:

This error occurs because Advanced Diary 9.0 attempts to initialize Windows DirectShow media capture features (used for audio/video diary entries or voice notes) through qcap.dll. Wine's built-in implementation of qcap.dll often causes memory access violations when querying Linux audio/video devices on startup.

Here are the step-by-step methods to resolve the issue:

Method 1: Disable qcap.dll via Wine Configuration (Recommended)

Disabling qcap.dll prevents Wine from loading the buggy video capture library while keeping the rest of the application fully functional.

  1. Open your terminal (Ctrl+Alt+T).

  2. Launch the Wine configuration utility (replace ~/.wine with your custom prefix path if applicable):

    Bash
    winecfg
    
  3. Navigate to the Libraries tab.

  4. In the New override for library dropdown box, type or select qcap.

  5. Click Add.

  6. Select qcap from the Existing overrides list and click Edit....

  7. Choose Disabled, then click OK.

  8. Click Apply and OK to save and exit.

  9. Launch Advanced Diary again.

Method 2: Install DirectShow Native Libraries via Winetricks

If Advanced Diary requires media features to function properly without crashing, install the native Microsoft DirectShow runtime components:

  1. Ensure Winetricks is installed:

    Bash
    sudo apt update
    sudo apt install winetricks
    
  2. Install the necessary DirectShow and media runtime components into your Wine prefix:

    Bash
    winetricks directshow quartz
    
  3. Restart Wine and launch Advanced Diary.

Method 3: Clean Wine Prefix (If the error persists)

If you previously installed 64-bit components or incompatible DLL overrides, creating a clean 32-bit prefix often fixes legacy Windows application compatibility:

Bash
WINEPREFIX=~/.wine_diary WINEARCH=win32 winecfg
WINEPREFIX=~/.wine_diary wine /path/to/AdvancedDiarySetup.exe
