Hello seongha lee,
I am following up to see if the proposed solution regarding the Qt framework rendering conflict resolved the blank window issue with the Helix Core installer. As previously analyzed, the white screen followed by an immediate crash is a specific symptom of the installer’s GUI failing to initialize hardware acceleration, which is effectively bypassed by running the installer via Command Prompt with the set QT_QUICK_BACKEND=software environment variable active. If you have not yet attempted this command-line execution, it is the critical step to override the display driver conflict.
However, if you applied that fix and the executable still terminates silently after two seconds, we must look at Windows security permissions. Right-click the p4vinst64.exe file, select Properties, and ensure the Unblock checkbox at the bottom of the General tab is checked; Windows often sandboxes downloaded installers (Mark of the Web), causing them to silently fail when they attempt to unpack temporary files. Additionally, verify that your antivirus or Windows SmartScreen is not heuristically terminating the process.
If the issue has been successfully resolved, please consider accepting the answer as it helps other people sharing the same question benefit too. Thank you!
