Cannot activate window/remove focus from Remote Desktop

Doesn't. Your macro works on my computer. QM 2.4.3.8, Windows 10, Excel 2003.

In Options also should be selected Administrator or uiAccess, not User.

Maybe win("Microsoft Excel" "XLMAIN") finds wrong window if there are several windows that match "Microsoft Excel" "XLMAIN". Try to minimize and restore it (in macro).
