litedbview 4.0.0 right menu in win7 about litedbviewer HOT 1 CLOSED

Unless you specifically select the 4th version to open a file, a default double-click tries to open it in v3.0. I mentioned this behavior in the release description:

At this moment, LiteDBViewerVersionSelector can't differentiate between LiteDB 3.x and LiteDB 4.x files. Please rename your file to .db4 if you want to open it directly with double-click.

Or change the program in charge of opening .db files by doing this:

The reason for this is that the file version between LiteDB v3 and v4 didn't change. So the right move is to make LiteDBViewer 4 to open both versions v4 and v3. However, LiteDB v4 is still in beta and for the software to act right we need to wait for the stable release.
