If you have a Windows operating system, suggest you un-install the present copy and re-install using Brady’s link above. It is too difficult to install OpenEMR and XAMPP separately, so avoid that route. Choose Option 1, Installation as service and follow instructions to the letter. If you must, print the instructions beforehand.
For explicit instructions regarding the XAMPP Control Panel, see the Recovery section of this unrelated Wiki article.
