Hello,
we are electricians who sell and install Borehole Pumps, we've found a solution to the damaged file issue. We hope this can help everyone
Try to go to C:\Program Files (x86)\Common Files\Adobe AIR\Versions\1.0
right click on "Adobe AIR Application Installer.exe" and click on "Run as administrator" then find and open the NinjaInstaller .AIR file
(if this first attempt was not positive, please keep holding Ctrl button while doing this procedure)
If this doesn't work it has to be identified the type of problem.
After you try to install file, please head to these folders and open the log file:
Windows XP: C:\Documents and Settings\<username>\Local Settings\Application Data\Adobe\AIR\logs\Install.log
Windows Vista/Windows 7/Windows 8 and 10: C:\Users\<username>Appdata\Local\Adobe\AIR\logs\In stall.log
Here you can find in the last row the problem.
Most cases is due to digital signature problem in the ninja file: you can solve moving the system date prior to 30 October 2017 or to actual date or (better).
If you need, feel free to contact

Wish you a nice day
