Windows defender - too keen?

We have become aware of people having trouble installing anything (not just our app!) on their Windows 10 computers. Symptoms include being told the hard drive is full during installation, or messages about Favorites folder when the app is running.  This is Windows Defender being ruthless about what it allows you to do. In some cases it has been known to block installs completely, even of Microsoft’s own products such as Office!
If you have trouble installing, Defender can be turned off temporarily during install. That will allow you to install properly, and the desktop icon will be created without the (incorrect)  ‘drive full’ message.
Defender can and usually should be turned back on afterwards.
However, if you then get message after message about ‘favourites’ folder being used (which is a normal part of windows use), you may want to grant our app permission to run unimpeded.
To do that for WinStitch (or any other trusted application), you need to ‘Add an Exclusion’
  • Go to Start  > Settings Updates & Security  > Windows Security Virus & threat protection > Virus & threat protection settings > Add or remove exclusions.
  • Under Add an exclusion, select the files, folders, file types, or process. The exclusion will apply to subfolders within a folder as well.
  • Select C:`\program files x86\winstitch 20xx\winstitch.exe
