GNS430 will not reinstall to new computer

I have been trying for three days to reinstall the X-Plane GNS430 from a Windows 10 to a new Windows 11 computer. I was able to reinstall the GNS530 and both of the GTN750/650.

But for some reason the 430 will not download normally. If I get it to download it does so with size 0KB and with a note 'failed'.  The file then disappears off the computer if I try to run it. If the other three RXP units download and install with no problem then it only makes sense that there is something different going on with the GNS430 file. So far the support at Flight1 has not been of any help other than to validate my account is good and the software has been reset.

Can someone at RXP be of any help...or send me the file in an email?

Thanks,

Alex
