Just took a quick glance – you’ve probably been down this road already: I noticed this:
“Razer Synapse is our unified configuration software that allows you to rebind controls or assign macros to any of your Razer peripherals and saves all your settings automatically to the cloud.”
Seeing “the cloud” makes me think of one possibility: if either your computer or router is blocking the ports (probably undocumented) that are used by the software to connect the devices to the ‘cloud’, it might be a reason for it spazzing out.
If you could get your computer on the (unsafe but works) DMZ in your router (opens ALL ports), it might work.
Another thought: running the installation software in Administrator mode. [right click, run as Administrator].
I mention it ’cause those are two weird solutions that cover a lot of unexpected problems.
[this also means disabling firewall on your computer too – forgot to mention that too] – It’s a shot in the dark: some things that work on one computer don’t work on another… but it’s something to try.
Oh and final thought: if you -do- get it working, it’d be worth figuring out what ports it actually uses, get yourself off the DMZ, do port forwarding on the ports it uses, put your firewall back (if you have one), only ’cause your computer will be naked to the Internet.
I feel like I ‘have to’ say that. I’ve been running my computer exposed for years. tongue emoticon
