System requirements
Preparation
Remove third-party antivirus and anti-cheats Kaspersky, Avast, ESET and the like, plus FaceIT and Riot Vanguard, conflict with the loader. They must be uninstalled, not just paused.
-
Open Settings → Apps → Installed apps (or Control Panel → Programs and Features).
-
Uninstall any third-party antivirus (Kaspersky, Avast, AVG, ESET, 360, Malwarebytes, etc.). Pausing or disabling is not enough — the antivirus driver stays resident.
-
Uninstall the FaceIT AC and Riot Vanguard anti-cheats if present — they block third-party software at the kernel level.
- FaceIT is the CS2 anti-cheat, Vanguard is the Valorant one. If you don't play those games, they are safe to remove.
After removing an antivirus, restart the PC — some of its services only unload after a reboot.
Fully disable Windows Defender The #1 cause of "it won't launch". Disable it for real: manually first, then remove it from startup, reboot, and finish it off with Defender Control.
-
Step 1. Turn protection off by hand. Open Windows Security → Virus & threat protection → Manage settings and switch every toggle off:
- Real-time protection — Off.
- Cloud-delivered protection — Off.
- Automatic sample submission — Off.
- Tamper Protection — Off. Turn this one off first, otherwise the others switch themselves back on.
-
Step 2. Disable reputation-based protection. In Windows Security → App & browser control → Reputation-based protection → Settings, turn everything off (SmartScreen, potentially-unwanted-app blocking).
-
Step 3. Remove Defender from startup. Open Task Manager (Ctrl+Shift+Esc) → Startup apps tab, find Windows Security notification icon and click Disable.
-
Step 4. Restart your computer. This is mandatory — some Defender services only unload after a reboot.
-
Step 5. Finish with Defender Control. Download Defender Control (archive password: r1xon), run it as administrator and click Disable Windows Defender — the tile turns red.
- If your antivirus deletes the utility itself, protection is still active — go back to step 1. The file ships zipped on purpose so Defender can't wipe it before it's disabled.
Don't skip steps 3–4. "I turned the toggles off but it didn't help" almost always means Defender came back after restart because it was left in startup.
Launch
-
Disable Windows Defender and antivirus software — otherwise the loader archive is deleted while unpacking.
-
Download the archive and unpack it into its own folder, for example C:\Lovec. The archive password is 123.
-
Run the installer as administrator and create a profile — pick a login and a password.
-
Paste the license key from the email, activate it, then log in with your credentials.
-
Launch Russian Fishing 4 and go back to the loader — with the game running, click your build's card.
-
Wait for the injection and press Insert in game — the software menu opens.
Problems & fixes
The loader does not start or closes immediately
The loader must be run as administrator. If that does not help, disable Windows Defender completely, uninstall any third-party antivirus and the Faceit AC and Riot Vanguard anti-cheats. Make sure Visual C++ 2015-2022, .NET Framework 4.8 and DirectX are installed.
The menu does not open on Insert
Wait up to a minute after entering the game — the menu does not come up instantly. The game must run borderless or windowed. On keyboards without Insert use the on-screen one: Win + R → osk → Enter.
After entering the key the loader asks to synchronise time
Open Settings → Time and language and press "Sync now". The loader checks the time against the license server, and a few minutes of drift is already enough to break it.
A Connection error appears after entering the key
The license server is unreachable from your network. Run the loader with a VPN on — that is enough; the VPN does not affect the game itself.
A No VMX, TPM, Legacy BIOS or Secure Boot error
The loader checks the BIOS. Enable virtualization (VT-x on Intel, SVM on AMD), turn TPM and Secure Boot off and switch the BIOS to UEFI mode.
A Bad HWID error
A copy of the loader is still on the PC — it may only run from the flash drive. Delete the file from Downloads, from the desktop and the unpacked archive, then empty the Recycle Bin. If there are no copies left, the key is bound to different hardware — support resets that.
FAQ
Auto-fishing does not catch anything
First place the rods, cast them and step a couple of metres away. Toggle the features strictly bottom to top: multiple rods → load protection → auto bottom fishing.
How do I filter out small fish?
Pick the species in the filter and set a weight range. Fish outside the filter physically cannot bite.
Still stuck?
Run R1XON Checker first — it pinpoints most launch problems in 30 seconds. If it still fails, attach the checker report to your support ticket and we’ll sort it out fast.
