Occasionally people have trouble installing my desktop app. This occurs whether they are installing for the first time, or updating either manually or via the app's auto updater. The result is the following error:
"The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author."
Usually one or a combination of the following steps solves the problem:
- make sure certificate is current
- if certificate is new, make sure the last used certificate is correctly migrated
- check that your computer's system clock is correct. Correct the date and time if it not current.
- make sure you have the latest updates for your machine eg latest Windows updates for Windows machines
- install the latest version of the Adobe AIR runtime (download from http://get.adobe.com/air)
- uninstall the app if it is already installed
- make sure the application folder does not exist (in, for example, c:\Program Files or c:\Program Files (x86)). If it does exist, delete it.
- empty the Trash (Mac OS) or Recycle Bin (Windows)
- try installing the app again
But every now and then the problem persists, and I am currently experiencing such a case with one user (the rest of the users seem to be able to install the app fine). I have pasted their installation log file below, and I was wondering if you know what causes and how to fix any of the errors below:

Thanks for your time and help.
