Yes, but as @Joe91 said, there is no need to uninstall first.
No data is stored in the application. All your accounting data is stored in a business data file (one for each business if you have more than one). The new program will call the same data the old program stored, reformatting it if necessary for intervening feature additions.
Have you recently forcibly removed Microsoft Edge from your computer? I know in the past when I’ve tried to install Manager Desktop on a Windows 7 computer without Internet Explorer, it refused to run.
No I didn’t remove anything from the laptop. I have now uninstalled and re installed manager and it still won’t work. I have given up and am using my desktop with no problem.
