Can't launch program

[illusive]

Description of problem or question:
Right after installing the latest update, the program won't launch any more.
I receive an error message window with a completely empty text box, so no information is provided.
Uninstalling and re-installing doesn't help.

It used to work just fine. What do I need to check?


HandBrake version (e.g., 1.0.0):

1.1.1


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Windows 10 Home (fully updated)


HandBrake Activity Log ***required*** (see How-to get an activity log)

No code since it won't launch.

Code: Select all

Please replace this text with the contents of your log file between the two code tags - OR -  provide a pastebin URL in place of these 3 lines.

Unfortunately there is no known way to fix this short of re-installing windows currently.

It's not something we can reproduce here, so it's probably related to specific hardware or drivers installed on the machine that's causing this. So any details there would be useful. We've had a few reports but so far haven't got enough data to see any patterns.

Even if the dialog box is empty, have you checked to see if there are any messages in the Windows Event Viewer?

I have the same problem. Just updated to v1.1.1 and it will not start. just a large empty box with a red ! and no information in the box or in Windows Event Viewer logs.
Currently running Windows 10 x64 Professional
done a full system scan and it states that windows is fine.

have to revert to previous version until its sorted out....

I have noticed though that the nightly build "HandBrake-20180905-d3e071f_x86_64-Win_GUI.exe" runs ok

@illusive, sorry, Mis-read. I thought you meant a total blank window, not blank error dialog. Blank Window is an unknown. Blank error, try pressing copy and see if the contents of the error are put on the clipboard.

otherwise, try the nightly.

copying to clipboard from empty box gives the following:
An Unknown Error has occurred.
System.NullReferenceException: Object reference not set to an instance of an object.
