KAL Online engine.exe Error: Check the FAQ and Inspect the File

[ice]

A KAL Online engine.exe termination has several possible causes in the official troubleshooting guidance. An antivirus alert should be inspected separately rather than assumed to be a false positive.

Check the documented causes

The official KAL Online System FAQ identifies five areas to check when an engine.exe error terminates the game:

• Graphics drivers
• Antivirus or virus-scanning software
• Motherboard software
• Sound-card drivers
• DirectX

The same FAQ says that a program bug may generate an exception.txt file in the KAL Online installation folder. Preserve that file if it exists.

Inspect engine.exe with Sigcheck

Microsoft Sysinternals Sigcheck can display file hashes, the catalog name, and the signing chain:

Code: Select all

sigcheck64.exe -h -i "C:\Games\KAL\engine.exe"

Sigcheck documents -h for showing file hashes and -i for showing the catalog name and signing chain.

Sigcheck can also query VirusTotal using the file hash:

Code: Select all

sigcheck64.exe -h -v "C:\Games\KAL\engine.exe"

The -v option performs a VirusTotal query based on the file hash. Adding the s modifier permits Sigcheck to upload files that VirusTotal reports as not previously scanned.

Submit a suspected false positive

If a Microsoft security product classified the file as malware and you believe that classification is incorrect, use the Microsoft Security Intelligence file-analysis portal. The portal accepts suspected incorrect classifications and provides submission history with detection details and analysts' determinations.
