I have the same problem. Thought I'd chip in. After seeing it's a permissions issue , and I'm running Win 10 Pro, I decided to look at the security settings for the folder: However this software is installed, it's not granting users with the modify permission on the folder and its contents, even though it's installed into ProgramData. For anyone not understanding security rights in Windows I suggest reading: https://msdn.microsoft.com/en-us/library/bb727008.aspx 'home' users won't be able to change these settings, typically, for some reason viewing security permissions like this and clicking 'advanced' to take ownership of the folder and its contents is usually reserved for 'pro' versions of windows. For some reason, when the software installs, it's setting the permission as SYSTEM, so even Administrators may not be able to consistently have write access to this location After clicking 'Change' and setting it to 'users' in the box that appears, voila I can change the config. You might want to look into what privileges you've got set to elevate to when you're installing the software and/or consider running a powershell/command script to fix the permissions after install.
