Hi,

This is an issue caused by the "mark-of-the-Web" on downloaded files that blocks the addin from being installed.

I've added some instructions in the Readme file on how to solve this issue.

Alternatively, here's a batch file that does the same thing:

powershell.exe -NoProfile -NonInteractive -Command "Unblock-File *"
start OutlookCloseToMinimize.vsto
