1: Failed to write configuration: Failed initialize settings instance

[JonnyBrando]

Issue and Steps to Reproduce

Installing 0.4.x works fine.

Fresh install of 0.5.x works fine ON A NEW SERVER with my current config.

If 0.4 has been on a server, the installer fails when building the nsc.ini file.

Happens when upgrading. Happens if 0.4.X is uninstalled/service removed/folder removed. Same error.

MSIEXEC /I <PATH>\NSCP-0.5.2.41-x64.msi /LOG <PATH>\install.log /NORESTART REBOOT=ReallySuppress

Expected Behavior

Installer should be able to read/leave, rebuild, or create the nsc.ini file without issues

Actual Behavior

Installer proceeds, unpacks new files, does read the INI file and update the installer appropriately, but crashes & rolls back
