What are the best practices for troubleshooting software installation and compatibility issues?

I’m interested in learning how other users approach software installation and compatibility problems, especially when an application works correctly on one system but behaves differently on another.

Some things I usually check first are:

• Operating system and application version
• Required dependencies and runtimes
• Available disk space and permissions
• Whether the issue occurs with a clean installation
• Driver or system compatibility
• Error messages shown during installation or startup

For those who regularly troubleshoot these issues, what is your usual step-by-step process for identifying the root cause?

I’d especially appreciate practical troubleshooting tips that can help avoid unnecessary reinstalls or configuration changes.
