Reading File Error

Hi every body,
Sorry for my poor English.

I have a Program 32-bit from time of Windows XP. In Windows 8.1 it is working normaly, no issues at all.
In Windows 10, with UAC Enabled, the Programm starts but when I try to read/save its configuration file therre comes a error and I have to close the App. I can not work, something is preventing me from working there.
With UAC Disabled via Registra (EnableLUA=0) it works normally, but other things in Windows stops working.
I tried to Install everything related to another Partition (far away from C:\ ) but that does not help.

Is there a solution for this? Is that a Problem with "Rights" or so?
That general Locking and Blocking of Programs and Files is driving me crazy.

Have you tried starting the program by right clicking the link and selecting Run as Administrator? This might force the program to read/save its configuration file. If it works you can set up a shortcut to it and change the properties: on the Compatibility Tab you can tick the box to always run as administrator.

Thank you for your answer.
Good point. I had not thought about that. I tried your sugestions but that Control app is located in the Control Panel and that option is not available for App there.
In the mean time I solved the Problem.
The files belonging to the Configuration are installed in Drive C:\ and was not installed in other Partition as I choice by the time of install . I think it must be on Windows Partition. Any way, I went to the Folder containing the files and took the OwnerShip and gave all rights to every user on Network. Now it is working.
