Environment Variables Not Set After Command Line Installation - Phoenix for 3ds Max 2026

Phoenix Phoenix :: Issues
1

We’re experiencing an issue with Phoenix for 3ds Max 2026 after performing a command-line installation. The environment variables PHX_FOR_3DSMAX2026_BIN and related Phoenix variables are not being set properly.

Error Message:

The PHX FOR 3DSMAX2026 BIN environment variable can not be found. Please reinstall Chaos Phoenix!

Setup Details:

  • Installation method: Command line installation ​
  • Software: Chaos Phoenix for 3ds Max 2026
  • Issue: Environment variables missing after installation

​Has anyone encountered this issue with command-line installations? Are there additional steps required to properly configure the environment variables when not using the GUI installer?

Any help or suggestions would be appreciated.

Hey,

Does it work if you use the absolute paths for the file locations in the config.xml file?

Also, could you try with quiet=1?

Thanks!

Hey! It works perfectly with quiet=1. I thought I had tested it before, but apparently I was mistaken. Thank you so much!
