Can installed programs conflict with each other?

You should not be concerned with programs conflicting after being installed. It's very unlikely for a program that is being installed to conflict or cause issues with other programs that are already installed. Often many conflicts occur between two programs while both of them are running. If problems do occur after installing a program, try the below suggestions.

1. Make sure the software developer has no updates are available for the newly installed program or the program generating errors. If updates are available on the developer's web page, install all available updates.
2. If an older installed programs stop working after installing a new program, try reinstalling the older program.
3. If the new program is getting errors after being installed, and you've tried the above steps, try reinstalling the new program again.
4. Finally, if Windows is getting errors after installing a new program and uninstalling the program does not fix the issues, try reverting back to an earlier backup of Windows.
