Crash on starting with a lvc file (1.4.1.1449)

It is again impossible to save configuration to a lvc file, and re-open it later.

It is 6 months that we bought several licenses of the V2, but it is still useless.

Any way to convert V2 licenses in V1 licenses?

I don't understand why you created this V2 version, the only real new "feature" I have seen it that it is never working correctly!

This bug is fixed in 1.4.2 which is to be released today.

You can create Log4View V1 license files from Log4View V2 license keys here:

log4view still crashes on startup (using 1.4.2 on windows 10). I already reinstalled log4view, no success.

Please send your lvc file to support@log4view.com

Even if I start without lvc file, it crashes:

Please start Log4View and keep the Ctrl-Key pressed until Log4View is running.
This prevents that the last settings are loaded at program start.
Does this fix the issue?

Yes, thank you.
But loading my lvc file still makes log4view crash, had to recreate my config. Now it works.

Now, it seems to work correctly, thanks.

But I still have the endless loading... popup when I got a "Could not find logfile xxxx" error. I don't always has all the files declared in the receivers. With v1, I just needed to close the error popups, after that it was working, but v2 is blocked on the Loading... popup.
