Need help with TP-link Omada software

We have a number of sites which use TP-Link Omada EAPs. These have been set up a number of years ago using the Omada controller. I have since reformatted my PC, which deleted the program and all the files. I never made a backup, but do have the source files from the original PC, but when I put them in the same location as the source files on the new client, the client does not open. I have also tried downloading the client that was used at the time, but the same issue occurs. Any help would be very much appreciated - happy to pay a decent amount to get it done as it would save quite a bit of time when it comes to re-configuring them all!
