Description

Description

On Windows, setting the OPENCODE_INSTALL_DIR environment variable does not affect the installation location (e.g. D:\215--Python\110--exe\080--OpenCode\). The installer ignores the specified path and always installs the binary to the default directory (e.g. C:\Users\xxx\AppData\Local\Programs\@opencode-aidesktop).

Plugins

no

OpenCode version

v1.18.18

Steps to reproduce

Set OPENCODE_INSTALL_DIR as a Windows user environment variable (e.g. D:\215--Python\110--exe\080--OpenCode) via System Properties → Environment Variables
Open a new terminal and run the install command
The binary is installed to the default path instead of D:\215--Python\110--exe\080--OpenCode
