What's Wrong?

I reinstalled the WSL 1 version of Ubuntu 24.04 under Windows. So my system is clean. Executing curl -fsSL https://claude.ai/install.sh | bash returns the following:

code@W10-20240815257:~/.claude/downloads$ curl -fsSL https://claude.ai/install.sh | bash
Setting up Claude Code...
bash: line 151: /home/code/.claude/downloads/claude-2.1.83-linux-x64: cannot execute binary file: Exec format error

uname -m
x86_64

What Should Happen?

Should be able to install Claude Code successfully.
