HandBrake Activity Log required (see https://handbrake.fr/docs/en/latest/help/activity-log.html)

The log files are empty, probably since the app crashes before logging can begin. (refer stack trace)

PS: If it's because my Windows version is too old (not even anniversary update), please tell me which is the latest version which will work with it.

Are you trying to run this on a 32bit version of windows?

[JediRhymeTrix]

@sr55 No, it's 64bit. Updated the main post to mention the same.

I'd suggest re-installing .NET framework 4.6.2 or later, rule out any framework level problems as you should not be seeing this.

[sr55]

I'm not sure that'll fix your problem, I suspect it'll just fail somewhere else now but it's worth a shot when the next nightly is posted.

I do still suspect you've got an issue on your system, probably with .NET so it's worth re-installing 4.6.2 anyway. The issue shouldn't ever happen in normal operation.

If I don't hear back in a few days, I'll consider this closed as I don't have anything more to go on.

Cheers

I've tried re-installing 4.6.2 as well as updating Windows to 1803 with .NET 4.7.1 but I still get the same exception.

[sr55]

Any different error or better result with https://handbrake.fr/nightly.php ?

[JediRhymeTrix]

Tried the latest nightly, Same issue.

[sr55]

Can you post the error please, I suspect it's not identical.

[JediRhymeTrix]

My bad. The exception thrown by the nightly was regarding not being able to read the presets. I uninstalled the stable version and deleted its AppData and could get the nightly to launch without crashing. I'm currently running an x265 encode to see if it's stable enough. But as far as this particular issue goes, I think it was just an issue with the AppData which wasn't properly conveyed by the error message.

[sr55]

Fair enough. I'll consider this closed then. The nightly is closed to 1.1 so it's not any less stable.

Constant braking changes with Win10 updates already made the Classic Shell developer to call it quits ... not sure what future holds for Win10 as more and more Win32 API stuff gets deprecated.

The fix is to completely remove the appdata/roaming folders for handbrake.
