I'm not sure how your system is setup, but the %AppData% folder in Windows is usually hidden folder located in C:\Users\<username>\AppData, which contains user settings for applications (runtime state, app settings, user preferences, reference content and other settings).
Applications are usually installed in C:\Program Files or C:\Program Files (x86) folder depending on the application.
Yes. I know. But some apps install in AppData too. More often with open source apps. Python, Pycharm and Git are 3 examples.
Just a tip, as far as being hidden, you can go to it easily with %appdata% in type here search next to Start.
Update: our I.T. department is looking at it to find out why this happens with TestComplete.
