I have this wireless mouse software/driver that is designed to run on Windows 8 and later versions, that I want to run on Windows 7 machine. The software is using Bluetoothapis.dll for the bluetooth functionality, which is not available in Windows 7 and this is preventing the program from running with a missing dll error. I have opened the exe file in hex editor and yes, there is a bunch of BluetoothGATT calls. I tried manually adding Bluetoothapis.dll and all the dependent dll-s to the installation folder, but it ends up with a DEVOBJ.dll error and I don't want to mess with that one. Is there a way to ignore the missing dll error via Windows and run the program anyway or something I can do to the exe file itself? I am using the mouse in 2.4 GHz or wired mode so I don't care about bluetooth connectivity.
