Hi Petrus, and welcome to the forums!
If you no longer have the setup-file (which, if I understand you correctly is your problem?), you needn't worry, AGEOD offers good support when you have purchased the download version through the AGEOD online store.
Simply send the details of your purchase to firstname.lastname@example.org
, and you'll get further help from there
