Mac Will Not Open Premiere

Recently I had to do a software re-install on my late 2015 Mac-Book Pro. Once I had re-installed the Mac I re-installed all my apps. It was all ok until I went to open premiere and it says "can not open adobe premiere" I kept trying but it wouldn't work. So I tried to delete and re-install yet it claimed that I still had it installed and wouldn't let me install it again. I went a step further into Daisy Disk to try and remove all files liking towards the app, yet it still will not let me re-install.
