Hello. I am using Win 8.1 on the laptop and on the desktop
Downloaded Windows version of Mailspring and … Installation is unsuccessful 
Download Win version again… still the same problem.
updated OS with the latest updates, restarted the desktop… STILL THE SAME
Downloaded WIN version on my laptop - STILL THE SAME - Installation failed.
Tried to use “Run as Administrator” - STILL THE SAME.
This is rather frustrating
Would appreciate your support in resolving this matter.
Kind regards,
