Hello. I used your company’s two-way controller, the software used is the smart one card pass management system (FCARD 3000T) V7.5, and I bought a set of four-way controller some time ago, and the software is the smart one card pass management system (FCARD) 3500T) V5.36, after installation, the previous 3000T cannot be used, and the 3500T is deleted, it is still the same, how can I solve it?

Hello, please reinstall the FCARD3000T management software, please back up the data before installation to avoid data loss.
