Windows includes a security protocol called Data Execution Prevention (DEP) that stops applications from running code from protected memory areas. You can add an exception for the installer.
Uncheck "Automatically manage paging file size for all drives".
If provided by the repacker, check the option box to ; this stabilizes data streaming and prevents the background decompression processes from crashing due to memory spikes. 5. Verify Content Hash (Torrent Recheck)

Third-party security software (especially AVG, Comodo, Kaspersky) and Windows Defender are the #1 cause of this error. Right-click your antivirus icon in the system tray and choose to disable it temporarily. After installation, immediately re-enable your protection.
Based on community reports and analysis, the failed to start error typically stems from one of the following issues:
If the file is corrupted, no fix will work.
