# SmartFoxServer 2X v2.18.6 cumulative patch

PLEASE NOTE: this cumulative patch works exclusively with SFS2X 2.18.x. If you're not currently running version 2.18 install it first, then apply this patch. SFS2X Download page

## How to use

- Unzip the patch and copy the decompressed folder inside your SmartFoxServer_2X/ installation folder.
- Open the patch folder.
- Run one of the three launch scripts based on the operating system in use:
  - Windows: double click the install-win.bat file
  - Linux: from a terminal run the install-linux.sh script
  - macOS: from a terminal run the install-osx.sh script

NOTE:
Under Windows 10/11 the default Zip utility will create an additional folder with the same name of the .zip file, if you extract the file from the contextual menu. We recommend double clicking the patch file instead and dragging the main folder to the SmartFoxServer_2X/ directory in your drive.
