Endian 3.0.5 is on 32 bit.
Endian 4.2.2 is on 64 bit.
Why do you want to install 4.2.2 over 3.0.5? That is not the way for upgrade!
If you have many rules created on 3.0.5 you can make a backup, download the backup on your PC, after a fresh install of the 4.2.2, during first setup you can restore the rules from backup (in case if your 3.0.5 can be started again; if not, fresh install of 4.2.2 and new rules).
The best solution is to use an ISO DVD.
I'm not upgrading 3.0.5 to 3.2.2. I'm doing a fresh install on the same hardware.
I have a backup of my 3.0.5 configuration and I also don't have that many firewall rules if i need to re-do them.
I don't have a CD/DVD ROM on this PC which is why I'm using a USB ISO to install.
Do you have any idea why I'm getting the error during the install?
