The website download is a GitHub master-branch source archive, not a versioned installer. A source archive can be useful when you want to review the code, study the project structure or work from a repository snapshot. Before using any PyOpenGL download, confirm where it came from, what branch it contains and whether the files match the project you expected.
Confirm the repository first
Check the repository owner, description, history, license and file structure. A PyOpenGL source archive should contain recognizable package modules, documentation and project metadata.
Inspect the ZIP before running anything
Save the archive in a normal user folder, scan it and look through the file list before running setup scripts. Avoid administrator or root permissions unless a trusted instruction clearly requires them.
# 1. Confirm repository and package names
# 2. Scan the archive
# 3. Review scripts and permissions
# 4. Test only in an isolated environment
Know when pip is the easier option
A repository ZIP and a package-manager installation are not the same workflow. For most Python projects, installing the named package with pip inside a virtual environment is simpler and easier to reproduce.
Use a virtual environment and normal permissions
Test source code in a disposable virtual environment. This keeps dependencies away from your system Python and lets you remove the entire setup cleanly if it does not work as expected.
Keep a simple download record
Note the source URL, date, filename and any trusted checksum. This small record helps you compare files later and makes it easier for a team to use the same source snapshot.
