The key part to look for in this error message is the "Action SaveFiles" text. This is the process that's attempting to back up the edx.ini file. The problem is the permissions on the edx.ini file, and by definition the whole ProgramData\EDX folder aren't set correctly, and the current user doesn't have permission to access or modify these files. The easiest solution is to just rename the ProgramData\EDX folder to EDX_old, and re-run the installer. To do so please follow the instructions listed below:
Open a file browser and navigate to c:\ ProgramData\EDX
NOTE: the ProgramData folder is normally hidden. In order to access the file you may need to paste C:\ProgramData in the bar at the top of the file browser that normally says quick access.
Rename the EDX folder to EDX_old
Re-run the installer
To verify the current version of SignalPro:
Launch SignalPro
In the menu bar navigate to Help>About
The installation should now finish correctly, and the permissions should now be correctly set for the {rgramData]EDX folder and all sub-folders and files. It may be at this point the user would need to manually copy the edx.ini file from it's location in the edx_old folder to the same location in the new folder to restore previous edx.ini file settings.
