Microsoft Defender is blocking Oscar 2.0.1

aren't there any exceptions in it's menu? sometimes these things happen. I have a forum I go to that will sometimes caution me that it isn't safe. but I can always over ride it cuz I know it's good.

maybe a similar deal with windows defender?

I can't get it to install either.

I D/L the program and try to run it as an Admin, but nothing happens. I shut down MS Defender and Nord.

Any suggestions? Thank You all.

I had completely shut down any and all protections... INCLUDING MS Defender.

When you say "nothing happens," how literally do you mean that? Is there no sign that the installer started at all? What computer are you using?

WELL.... I don't know why, but I tried the update installations again this morning..... and it worked !

A mystery to me.... but as long as it installed I am happy.

Thanks for the help all.

Great to see OSCAR continuing to get regular updates and improvements. The new features and data tracking make analyzing sleep apnea therapy data so much easier and more detailed. Thanks to everyone involved in keeping this tool running and updated!
