Upgraded from Windows 7 to 10 and can't install/run photoshop CS5

[rileym15705378]

Hello, I've been using photoshop CS5 for around eight years and recently updated my computer to Windows 10 after some hard drive issues. I now can't run CS5 even after running the application as an administrator and updating the compatibility version to Windows 8. I don't have the initial license key since it's been ten years since CS5 was installed on my computer and I can't find what email was used to register the software. What are my options here for reinstalling CS5 on my computer, can I find my license/registry key somewhere within the CS5 folders I have on my computer?

Thanks for the reply, the Belarc Advisor software doesn't show me the software licenses/keys for software that hasn't been installed yet. It's detecting adobe photoshop CS5 in the software version and usage section but it isn't showing me the key in the above software licenses tab. Appreciate your help though.
