There's a reason for using the PC connectivity Kit 3.0. Only this software package contains a DLL for updating the HP49G.

I installed the software without any problems on a Win10 x64 PC. Then start the software, the HP49 is not connected, and don't care about conectivity. Navigate inside the software to the directory with the .flash file and make, like described, a double click on the .flash file. This starts a separate update software in an own window.

The update software only supports COM1 and COM2, so make sure that your HP49G is connected to one of these two COM ports.

Follow the instructions how to update the HP49G.

I tested the process yesterday successfully with hpcomm-30r4.zip, com0com as Null-Modem Driver and Emu48 running a HP49G.
