I hope that you are well.
I understand your policy, as permissions can be a daunting task for system administration and I am not enquiring about support for system administration, although your software is, to my understanding, technically supposed to assist/complement system administrators with system administration.
I am concerned that your software does not offer any immediately-apparent logging so as to identify such problems and bugs.
Your software is quite good in its current form, however if there is an ongoing subscription, support is typically expected. I understand I am not a paying customer, yet.
I have provided the user permissions set as requested and in reference to the Remote Utilities Portable version of software, it has full access permissions. So I don't understand where you/the developers are claiming further Access Rights permissions issues specifically? I also have administrator permissions for the PC in any case too.
One main question in this case would be, upon installation of your software, what are the permissions required for the system to function as per the default configuration? Can you point me to the documentation that specifies this please? If the .MSI is to be deployed via Active Directory, I would think that the permissions would need to be configured before deployment?
