I just fixed this on Windows 10! I hope my solution works for you: Resolved error 35 and RS20 message.

The issue seems to be between cURL code of the server you are trying to download FiveM files from and windows.

  1. Goto Microsoft.com and install NetFXRepairTool or click https://download.microsoft.com/download/2/B/D/2BDE5459-2225-48B8-830C-AE19CAF038F1/NetFxRepairTool.exe

This will resolve the cURL side of the problem.

  1. Ensure you have deleted ALL previous FiveM files by opening up your file explorer> select drives you may have put files on and type “FiveM” into the search bar. Once the list is fully populated delete any files that are FiveM. (Note: Some of the files will give you error messages, that is fine skip those and continue until complete)

  2. Turn off ALL firewall and anti-virus. You may even have to uninstall your antivirus, even when disabled some of them tend to affect your PC still.

  3. Create a new folder on your desktop, label it “FiveM” (no quotations)

  4. Open up Microsoft Edge, not Chrome or any other browser. Type Fivem.net into the browser bar and select the client download. When the download finishes DO NOT OPEN IT! Instead Right-Click and go to file location which will most likely be your downloads folder. Copy the FiveM.exe into the empty folder you created in step 4 on your desktop.

  5. While Microsoft Edge is still open double-click or Run the FiveM.exe that is located in the FiveM folder on your desktop.

  6. Ensure you are not running FiveM.exe in administrator mode, it will not be able to complete the installation if you are. Be patient you may have to re-run the program a few times the download server seems to be a little slow and interrupts itself.

I hope this solution works for others that have endured the frustrations of trying to get into GTA RP. Please note It did not work perfectly the first time I had to rinse and repeat starting at Step 6 a couple times due to server stability. Once the stars “align” this should help anyone on Windows 10, possibly earlier versions as well.
