Check for updates for your NVIDIA, AMD, or Intel Iris card. If you recently updated and the crashes started then, try the "Roll Back Driver" option. 3. Disable GPU Hardware Acceleration
If optimization fails, you may need to move your database files (usually found in Documents\ArcSoft or %AppData% ) to a different folder and let ACDSee build a fresh one. Note: You will lose categories and ratings unless you have embedded them into the files (XMP). 5. Check for Windows Update Conflicts
Ensure your Windows is fully up to date, or try reinstalling the Microsoft Visual C++ Redistributable packages (2015-2022 versions are the most common requirements). 6. Isolating Corrupt Media
Press Windows Key + R , type %LocalAppData%\ACD Systems\Catalogs\ , and hit Enter.
ACDSee Ultimate relies heavily on GPU acceleration for its Develop and Edit modes. If your driver is outdated or a recent update is buggy, the program will snap shut. Go to Device Manager > Display Adapters .
