License Key but No Download

I bought a disc for Windows 8 a while back, and now that I am on Windows 10 I tried the disc again. Since the disc doesn't download anymore, I tried the site but I don't want to buy the pro version again.

Is there a way to insert the license key into the free version?

Or is it possible to go to the site and see if my license key is still valid?

you can download the Free version and insert your key to make it the Pro version.

if you have lost your key, check the email you were sent when you purchased the Pro version, it contains your key

or use this link to get the key resent to your email; <a href="https://www.piriform.com/support/license-lookup" rel="external nofollow">https://www.piriform.com/support/license-lookup</a>


or a support ticket can be raised from here; <a href="https://piriform.zendesk.com/hc/en-us/requests/new" rel="external nofollow">https://piriform.zendesk.com/hc/en-us/requests/new</a>

Thank you very much!
