Fluke 787 Cal Adj Procedure

Hello !!! I'm trying to adjust a Fluke 787 using the a Fluke procedure and a Fluke 787CAL module.

My workstation is running Windows 10 64bits and I am using a physical COM port not a USB to RS232 converter and the COM port keeps timing out.

The procedure revision I'm using is 1.1 and I'm running Runtime 8.1.7.3.

Sould I use a Windows 7 workstation or is there some kind of a workaround manipulation I can do to make it work on my current workstation??

Thanks in advance for the info!!!
