An admin window is blocking my clicks

What's happening

Windows doesn't let a program without administrator rights control one that has them. The RemoteAccessApp Agent runs as the person signed in to the PC, so while a window that runs as administrator is in front, Windows drops every click and key you send. Common examples are Task Manager on an administrator account, an installer, or a command prompt opened as administrator.

You can control these windows (move Task Manager around, click it, end tasks) when both of these are true on that PC:

• RemoteAccessApp is installed for all users (in Program Files, the normal install). The Agent then passes your clicks and typing through a small signed helper that Windows allows to reach those windows.
• Unattended access is turned on for the PC. Controlling administrator windows is part of unattended access; a session someone at the PC only allowed doesn't get it.

Otherwise Windows drops your clicks and typing while such a window is in front. You still see the screen, so the session can look frozen. RemoteAccessApp tells you, and says what's missing, with a message like this:

"(Program name)" is in front on this PC and runs as administrator, so Windows blocks your clicks and typing until someone at the PC closes it or clicks another window. Reconnecting doesn't change this. To control windows like this, turn on unattended access for this PC.

Fix it for good

• Not installed for all users: run the RemoteAccessApp setup on that PC again and choose Yes when Windows asks for administrator approval. Your settings and the PC's place in your account stay as they are.
• Unattended access off: turn it on for that PC (in the Agent on the PC, or from the Console).

Get going right now

• Ask the person at the PC to close that window, or just to click another window so it's no longer in front.
• If you started the program yourself, avoid running it as administrator when you don't need to.
• Reconnecting doesn't help: the window is still there when you come back. Switching to another relay location doesn't either, because Windows blocks the input on the PC itself.

Permission prompts, lock screens and Ctrl+Alt+Del

Windows also keeps remote tools away from its own protected screens: the "Do you want to allow this app to make changes" permission prompt, the lock and sign-in screens, and Ctrl+Alt+Del. Someone at the PC has to answer those, even with an all-users install.

If you choose Ctrl+Alt+Del from the Keys menu, RemoteAccessApp explains this and offers Open Task Manager instead, which is what Ctrl+Alt+Del is most often used for.

Updates don't need anyone at the PC

RemoteAccessApp installs its updates by itself with no permission prompt: an install just for you updates itself with your own rights, and an install for all users of the PC uses its update service. See automatic updates.
