Title: Need Synapse 3 installer files – Synapse 4 bricked 2x Naga Left-Handed Edition (CRP DISABLED)

Synapse 4 bricked 2 of my 3 Naga Left-Handed Edition mice (CRP DISABLED, firmware.bin mass storage). My last unit can't save onboard profiles reliably through Synapse 4 either. I need Synapse 3 to safely configure it.

Already tried:
- All official download links → redirect to Synapse 4
- Filehippo/Softonic bootstrapper → servers are dead
- Archive.org v3.3.0508 (2018) → too old for the Naga LH, and still tries to install Synapse 4
- Extracting the 2018 installer via 7-Zip → GUI/service EXEs only, no USB drivers, wrong version
- Offline install (network disabled) → installer refuses to continue
- OpenRazer (Linux) → can't write onboard profiles

What I'm looking for: If you still have Synapse 3 installed (v3.5+, 2020 or newer), could you zip and share the following?

- `C:\Program Files (x86)\Razer\Synapse3\`
- `C:\Program Files (x86)\Razer\DeviceDrivers\`
- `C:\ProgramData\Razer\Installer\`

Or better yet: the cached MSI packages from `C:\ProgramData\Razer\Installer\Razer Central\Packages\` or `C:\Windows\Installer\Razer\`

Open support ticket: #260325-000894. Also contacted Razer.sushi.boi regarding the bricked units.

Thanks for any help.
