yeah I know, thank you, it's an old unit that I use as a base now, there no new firmware after 4.61

here is the link for all firmwares, thank you

@sluggo Thank you for your assistance; however, the provided link does not offer any firmware for the SPS receivers.

Hello, did you find a solution ? I have an old receiver here and I want to upgrade the firmware to the version 4.61, do you have the file please ?

@goodgps you mean the trick is to ONLY use files that were created on the windows 7 not 10 machine.?ÿ Windows 10 will NOT grab old files to work with...
