I have no idea why you have two of them, but one Uninstall folder is ABSOLUTELY ESSENTIAL. You would be most unhappy in the future if you delete them now.
Also, you gave next to no sensible information, such as to what exact version of Photoshop you are referencing, whether you are on the subscription model, etc. It could be that you have both CC and CC2014, etc.
BOILERPLATE TEXT:
If you give complete and detailed information about your setup and the issue at hand, such as your platform (Mac or Win), exact versions of your OS, of Photoshop and of Bridge, machine specs, what troubleshooting steps you have taken so far, what error message(s) you receive, if having issues opening raw files also the exact camera make and model that generated them, etc., someone may be able to help you.
