Need copy of Creo platform agent 3.121 and PTC Diagnostic Tools

Hello there!

I am sorry to intrude here, but I have problem with unninstaling Creo platform agent 3.121 and PTC Diagnostic tools(which is propably some kind of similiar version as platform agent). The reason why I have this trouble, is because i unninstaled Creo 3.0 M080 which I had for some time, but i deleted the installation files and cannot unninstal Platform Agent 1.321 and that diagnostic tools. Would be anybody so kind and send me those files somehow?

Thank you very much
