+
+## 2025-03-26 - 2.6.4 - fix(setup)
+Improve installation process in setup script by cleaning up package files and ensuring a minimal net-snmp dependency installation.
+
+- Remove existing package-lock.json along with node_modules to prevent stale artifacts.
+- Back up the original package.json before modifying it.
+- Create a minimal package.json with only the net-snmp dependency based on the backed-up version.
+- Use a clean install to guarantee that only net-snmp is installed.
+- Restore the original package.json if the installation fails.
+
 ## 2025-03-26 - 2.6.3 - fix(setup)
