Unable to install Minimwatch

[IIII]

Dear Simoncn,

Thanks for your quick response.

EDIT :
Finally, by changing the permission access of my windows account, and by disabling again the windows firewall the Minimwatch icon turns now to yellow then green.
When I restart the windows firewall, the Minimwatch stays grey again.

How can I fix it definitively ?

If it can help, this is the Minimwatch log :

Thanks for your following up.
