ChatGPT - Advanced Diary 9.0 Access Violation at address 75D947DC

I was able to install Advanced Diary 9.0 on an Ubuntu Linux system with Wine, but every time I start the program I see the message "Access violation at address 75D947DC in module 'qcap.dll'. Read of address 5F505353." though the program then opens and seems to function normally.

ChatGPT Response:

That specific error is a strong clue that the problem is not with Advanced Diary itself but with Wine's implementation of Windows multimedia components.

The DLL mentioned:

qcap.dll

is the Microsoft DirectShow Capture library, which is part of Windows' multimedia framework (video capture, webcams, capture filters, etc.). An "access violation" in qcap.dll under Wine often indicates that the application is calling a multimedia API that Wine doesn't fully implement or implements differently. The fact that the program continues running normally suggests that this code path is optional—perhaps checking for available capture devices or initializing multimedia support.

Here are a few things you can try.

1. Check whether Wine is using its own qcap.dll

Run:

WINEDEBUG=+loaddll wine AdvancedDiary.exe 2>&1 | grep qcap

If you see Wine loading its built-in qcap.dll, that supports the idea that it's a Wine compatibility issue.

2. Try a native Windows qcap.dll

Using winetricks:

winetricks quartz

or

winetricks wmp9

depending on your Wine prefix and Windows version.

Then in winecfg:

• Libraries

• Add qcap

• Set it to native, builtin

Be aware that native multimedia DLLs sometimes introduce other dependencies, so this may or may not improve things.

3. Try a newer Wine version

If you're using Ubuntu's repository version, it's often behind current Wine releases.

Check:

wine --version

If you're on something like Wine 8.x, trying the latest stable or staging release (currently much newer) can resolve crashes in multimedia components.

4. Disable unnecessary multimedia initialization

If Advanced Diary has options for:

• webcam

• video notes

• audio recording

• scanner/camera import

disable them. Some Windows applications initialize DirectShow even if you never use those features.

5. Get a backtrace

If you're curious about exactly what's happening:

WINEDEBUG=+seh,+tid,+relay wine AdvancedDiary.exe &> diary.log

or more simply

WINEDEBUG=+seh wine AdvancedDiary.exe

The backtrace can show which function in qcap.dll is faulting. If the exception is immediately caught by the application and execution continues, it's likely the program is probing for a capability and recovering gracefully.

Since the application works...

Given that Advanced Diary opens and appears to function normally, this is probably a benign startup exception rather than data corruption or instability. Many Delphi applications (which Advanced Diary appears to be) catch access violations during optional subsystem initialization and continue running.

A few questions that would help narrow it down:

• What version of Wine are you using (wine --version)?

• Is this a 32-bit or 64-bit Wine prefix?

• Does the error appear before the splash screen, or only after the main window is displayed?

• If you run with WINEDEBUG=+loaddll, does it report loading Wine's built-in qcap.dll or a native Microsoft one?
