If you bought ODNT (Object Desktop) then it is free for you. Why you'd download from stardock.com I don't know, but I'd advise you to uninstall the trial and (use ccleaner) the registry links, or Revo uninstaller at medium strength and delete the values in bold font.
Then download and install Icon Developer from here:
https://store.stardock.com/login.aspx?ReturnUrl=/myaccount/products
That link you posted is for those who purchaed Icon Develoer. If you look closely at this link:
https://www.stardock.com/products/icondeveloper/downloads.asp
It distinctly ahows a "FREE" version. But when i install it and run it it says "You have 30 days left on this trial version"
I downloaded the CursorFK Free version and it's woking fine, no trial version popups etc....
