libPortMidi.dll problem

Hi,

When I try to install OM 7.1 on windows 11
I have a message :

libPortMidi.dll
Accès refusé

I really appreciate your help.

Hi,

This means you cannot install software on your windows 11. Do you have an anti-virus running?

Hi!

Yes I do

But when I desactivated the firewall it’s still the same message

So it could be that you don’t have access to your Program Files (x86) folder as a user.
Can you check this as administrator of your machine?
