Trouble updating Prime firmware

[informach]

Hi!, mark4flies:

Try, uninstall and erased, all data, in register, from PC, notebook, etc ...
You can use ... Advanced Uninstaller PRO (Free), from ... http://www.advanceduninstaller.com

Then, install Firmware, Connectivity kit and Virtual Emulator, from ... http://ftp.ftp.hp.com/pub/calculators/Prime/

Now, with installed Connectivity kit, connect your HP PRIME and download the Firmware.

Note: If nothing happen, try, install, the firmware, from other PC or, netbook.
