The old folder could not be removed because XAMPP was not uninstalled from the system yet. Running the uninstaller/trying to delete the files will not remove a Windows Service. If the service is running, those files are in use and the system will not let you delete them.
You can uninstall them manually via the command line then you should be able to install the new one and not have conflicts. If the old version is still running/loaded, it will not allow you to use it in a different location unless you reconfigure the control panel.
You can uninstall them manually be opening a command prompt (Start > Run > cmd) with admin privileges and running the following 3 commands (assuming you only had Apache, MySQL, and FileZilla installed as services):
- Code: Select all
sc delete Apache2.4
sc delete mysql
sc delete FileZillaServer
