Notes 6 and 7 couldn't run at same time

I’ve followed the instruction in the release notes to install Notes 7.0.2 on the same computer with Notes 6.5.5 installed. I can run them separately, however they can’t run at same time whatever which one launch first.

I remember it was working yesterday, somehow it doesn’t work now.

Any ideas?

Subject: what’s difference of notes.exe and nlnotes.exe?

I can launch notes.exe of 6.5.5 and nlnotes.exe of 7.0.2.Maybe different version of notes.exe shared something.

Anybody knows?

Notes.exe is a launcher for the Notes client. Nlnotes.exe is the actual client executable. If you want to run two different version of Notes at the same time you need to run one of them by running “nlnotes.exe” from the install directory. You may need to edit the desktop/program menu shortcuts by hand.
