Upgraded, but still trys to run the free version

I was running the free version of teamviewer then upgraded to a business version. But when I try to run the upgraded version a message comes up 'Did you mean to switch apps, Microsoft Edge is trying to start teamviewer 14' (which is what I was using before the upgrade.

Plus the only way I can get on the business version is start the free version then press 'activate licence' then I get on to it.

Any help Please
