Maybe I have the same problem?
I've been using the MiniVNAPRO for many years with no problem. Lately on a PC upgraded to WIN10. But after the Main Board of the PC broke  I've tried to install the JAVA SW on another PC with WIN10. Everything looks fine till I come to calibrating a short (open seems to be OK). The program won't go from 0%. I've tried for many days without success. I've even removed the harddrive from the broken PC and tried to start the SW from there but no luck. No knowledge of how Windows works.
It says vna/J version 3.4.7 (Java 1.8.0_291). Serial number of the box is 3180.
It works fine with Android SW, but the PC SW has some extra features that I'm after.
Any idea?

The upgrade should be done with an older vna/J version

I have the same problem with version 3.4.6, with Java 1.8.0_271, my OS is windows 10 and the firmware version is V2.3 21-05-2011. I tried to download firmware by following the video here:http://download.dl2sba.com/vnaj/videos/fw_upgrade.html but my tools menu is grayed out. I'm not sure what else to try.

Hi,
 
I am trying to use the miniVNA pro with VNA/J version 3.3.4, with java 1.8.0_241, my OS is Windows 10 pro, but I'm currently facing some issues.
The firmware version is V2.3 21-05-2011.
When I am trying to create a new calibration, the open circuit calibration seems to work well, but when it comes to the short calibration, the progression bar of the process is frozen to 0% and it never goes further than that.
On the contrary, when I start by the short circuit calibration, it works fine, but the next calibration doesn't work, no matter what the order is. The same happens when I start with the 50 Ohms calibration. And I've tried both modes 1 and 2.

Could you please help me to solve this issue ?

Best regards,

Guillaume
