System.NullReferenceException: Object reference not set to an instance of an object.

What were you doing when VidCoder crashed?

I did a clean install on Win7 64-bit. Every launch attempt fails with an "System.NullReferenceException: Object reference not set to an instance of an object." error.

Crash details

Thanks for the report. I put a fix in for 11.6 Beta that should improve the error message here. Can you let me know what it says on v 11.6?

The error now is:

VidCoder 11.6 Beta Portable System.DllNotFoundException: Unable to load DLL 'hb' or one of its dependencies: The specified procedure could not be found.

I'm guessing Win7 is not supported? If so, do you know the latest version which supports Win7? Thanks.

[RandomEngy]

Yes, that's right. For a while now, Windows 7/8 has been "run at your own risk". In the latest VidCoder beta I've extended the OS version error and block to cover Win7/8.

The latest version that supports Windows 7 is VidCoder 5.21.
