49. Disable This Program May Not Have Installed Correctly

Important Question! Can your PC Run Faster?

Alert messages are there for a purpose, mainly to let you know that something is not exactly as it should be. However, some alerts can trigger even though a problem has not arisen. The This program may not have installed correctly alert usually pops up when installing legacy software, i.e., an application that was developed for an earlier version of Windows. Unfortunately it also has a habit of popping up when the application you are trying to install actually has been developed for Windows 7 and, as such, it can then become a pain.

Disabling alerts can be counterproductive, but there are occasions when disabling the alerts is the only option. Whether you disable this particular alerts or not is entirely up to you. Only you can say whether it is causing you distress or not.
