Without internet, it will flash and quit (#804), then left a log file at %HOMEPATH%\lem.log:

After I connected to the internet, everything worked.

Is this the expected behavior?

Some cautious person would have a bad feeling about this.

[cxxxr]

certainly. This is strange behavior. Thanks for the report.

It seems to be this line:
