I found this bug today and it appears to occur on all of my 7.0.0.1 clients.
I installed the latest 7.0.0.1 Viewer on Windows 10 and also on some other machines for testing purposes.
The problem:
You can't run files (e.g. exe/bat) from the File Manager. The Remote File Execution Window does not appear.
I still can copy the filepath of the file that needs to be executed and use the "Remote Execution" Window to run my file but it gets annoying to do it all the time.
In 6.x I don't have this problem, I can execute files from inside the File Manager.
I hope this can be fixed.
PS: There are no logs for this bug in any of client/viewer logs.
