good day how can I have installed both versions of the program in window 7  Avidemux_2.7.5 VC++ 64bits 200626  and  Avidemux_2.7.6 VC++ 64bits   
have both versions installed in window 7

Copy the installation directory of an older VC++ build to another location (you may delete the maintenance tool, it is not needed), then install 2.7.6 VC++. This will uninstall the older version, but you have a copy which you can run from any location (at least from any local one).

Just never run both at the same time.
