Hi,Hello,
Thank you for your post.
You can find the download links for legacy versions such as 17 and 18 here: https://kb.parallels.com/en/5802
Please also note that older versions might not be fully compatible with newer versions of MacOS; please refer to this compatibility matrix accordingly: https://kb.parallels.com/en/114381

Since my mac already upgraded to the new macOS so I have to tag with parallels 20 and/or newer.
Pls help me with the way forward.
