Drivers should be located at C:\Program Files(x86)\Razer there will be folder(s) named PIDxxx and there’s a driver inside each folder (you can just put the main path and search subfolders when manually choosing driver location).

Hi, sadly that folder doesn’t exist. Has the mouse been discontinued and that’s why it doesn’t show on the firmware download page?

Synapse will install appropriate driver. If you don’t have Synapse installed, then install it, if it’s installed you might clean-reinstall it with the short manual below:

1. Uninstall Synapse
2. Download & run this tool: https://rzr.to/Tf53xj to remove any razer drivers/leftovers
3. Then restart your PC
4. After reboot install Synapse again (as administrator).

For the scroll wheel issue - you might try your mouse on another PC (without Synapse installed).

Thanks, that’s it working.

So I've tested the mouse on two other devices (Mac and windows) and the scroll does not work so assuming this is a hardware issue? its out of warranty, did you happen to know the rough costing (£) for a fix? Debating just buying a new mouse if expensive.

Many thanks for all your help so far. 

I suppose to add, is there any way to override in Synapse to allow me to change the ‘Repeat scroll down/up’ to scroll up and down and i’ll just use it that way? its not letting me change. Thanks

This should be overrideable. Have you got any screenshot of this>

If the scroll wheel is not working when connected to another PC, then it might be dead. You can try to disassembly the mouse and clean the scroll encoder with canned air and 100% IPA. But it uses 4-pin LK-E5 (optical) encoder which is hardly available.

Worked out the remap, added scrolls and turbo mode. i’ll use it like that for now - cheers

EDIT: it worked for a split second when I booted the PC then stopped hmm… disabled it for now and using the side scroll

Just had this same issue. One day mouse wheel working perfectly fine; shut down go to sleep then come back next day and mouse wheel scroll does not work. Side scroll mouse buttons and middle mouse button click still work. 

I’ve been having the same problems. Some days it works fine, other days it just doesn’t. The Synapse updater also doesn’t seem to work well. It downloads a few bytes, some times a mb or 2, then pauses, so I have to keep clicking resume download every few seconds. This has been an ongoing issue since I first installed the mouse. It seems to be a software issue, and honestly if it isn’t fixed this will be the last product I ever buy from this company.

Same thing happening to me. Bought my naga trinity today, opened it, connected it, installed it , updated it, restarted PC and the scroll wheel doesn’t work

I just solved this problem today. Seems if dust or dirt of any kind gets in around the wheel it stops working. Once you blow the dust or debris out of there it should work. Clearly this was a very poorly designed component on an otherwise great device.
