If the above uninstallation steps do not help resolve the condition, or if you would still like to install the specific Windows update (KB5124010) on your platform, our further investigation has found that the Power2Go crash on launch is caused by a malfunctioning and corrupted Windows OS component, msmpeg2ac3dec.dll, after the problematic Windows update is installed. This Windows update further causes conflicts and crashes with some third-party software (e.g., Power2Go) that may also use or rely on this specific Windows OS component.
To resolve the crash concern, here is a workaround for your reference that will prevent the specific and corrupted system component (msmpeg2ac3dec.dll) from being loaded by Windows OS.
To use the workaround, follow the steps below:
Download and extract the ZIP file from the following link.
Double-click the Disable_msmpeg2ac3dec.bat file to launch it, and allow it to make changes to the system configuration.
After the configuration is completed, reboot Windows and then check whether Power2Go can launch normally.
Note: To restore the changes made by this workaround to your Windows OS, you can double-click the Restore_msmpeg2ac3dec.bat file to start the restoration process, and then reboot Windows for the changes to take effect.
