The Issue

  1. You want to install the App on a sub site
  2. Opened ShortPoint Online App Dashboard
  3. Opened Installation
  4. Then pressed Install button
  5. Then the installation progress bar stopped and error message displayed: "The installation has been failed, please try again"


The Cause

  • If this was not the cause
  • Then the reason is a missing SiteAssets library which we need to add the App files and resources


The Solution

  1. Create new Site Assets Library on the sub site with the name "SiteAssets"
  2. Try again and it should work without any issue now
