Hello,
Welcome to Microsoft Q&A!
I'm stuck trying to deliver the .exe installer because of the URL format
URLs like Google, dropbox and OneDrive don't meet the URL requirements for the Store. It is suggested to build your server to host your app.
I understand your feelings. But for security purpose, signing your code is necessary for the submission. The store needs to make sure all the apps are security enough for all the users.
Thank you.
