I am connecting to a Windows 2012R2 terminal server in a domain. There are about 15 users that connect to the server RemoteApp collection to run Office 2016. They are all working except me. I was working fine until yesterday. I looked and no updates have been installed for more than 8 days. If I double-click on a local file (located on my desktop) the system acts as if there is no application setup. This works fine for all the other users. When I go to default applications on my system and look at file associations, it displays the collection application associated with the file, it also provides a + sign and "choose a default" as a choice. If I click on the + sign I get "there is no installed app" message. The entire line is grayed. I have logged into the terminal server and toggled the file association within the collection to off, saved it,, the ran the update for the collection on my system, then I toggled the file association within the collection to on, saved it,, the ran the update for the collection on my system, there was no change when I looked at default applications under file extensions. I removed the RemoteApp connection and recreated, no luck. I compared the file association to another machine. On the working systems the file extensions show the collection applications where my system is grayed out. I and all users are running Windows 10 build 2004. I have also attempted to run the Office cleanup tool, in the event there was something in the registry that was causing this issue. The cleanup tool found no instances of Office either installed via msi or one click or Office 365.
