I can't install .zxp through adobe extension manager

Hello, I had an issue with my computer and I reset it so when I reinstalled Dreamweaver and extension manager the same version I have but Adobe extension manager does not recognize Dreamweaver so when I try to install your products I asked me for Dreamweaver but it is already installed. So was looking through your forum and I found some solutions but not working. Like install DMXZONE extension manager. I did already but I can't install them. Only MSQLI Server behaviours but I can't install the rest ot them. I am afraid with this issue because Adobe extension manager has gone and I feel like I spend my money only for months. I was thinking buy your future update but how can I do it if I can't install them. For now I don't know what can I do. And it should be work because I have the same Dreamweaver version
