Likely Root Causes 


Root Cause 1 


Where you might not have any permission allowed to run the .exe executable . 


Root Cause 2 

Make sure UAC is disabled on the System 

To turn UAC on or off

  1. Open User Account Control Settings by clicking the Start button , and then clicking Control Panel. In the search box, type uac, and then click Change User Account Control settings.
  2. Do one of the following: To turn off UAC, move the slider to the Never notify position, and then click OK.



Root Cause 3 

Make sure all the AV and AV services are stopped / Disabled 


Root Cause 4 

May be there is reboot pending on the system due to any other software installation / Windows update . 

Please reboot the system and then try again for the installation 


Root Cause 5

All active users has to logg off there must not be other users has to logon to the system there some other user locked the installation files 


Root Cause 6 

You must need to check each of MSI's have full permissions under this folder .



You must need to check you are able to see the "Security" tab for each of MSI's and there is no permission  issues .

If you are unable to see the permission for any of the MIS's under this folder the installer will not launch . 



So make sure you are able to see the Security for these MSI's properly as below screen shot 



Try to take ownership of the files if you still have the Access is denied issue this has to be corrected by your System admin as for some reason you are unable to correct the permissions for required file and NTA installer will not start. 



Root Cause 7 

Most likely some other software is trying to access the MIS's files and not allowing to change the permission .


Such as an example of Kaseya agent running on the Orion server was blocking the MSI's files to access .


Kill the process from task manager > Rename the Executable file for the agent 








Or Disable the service and make sure non of them running on the system . 


If you still have the same issue and unable to start launch the installer . Please contact SolarWinds support.
