What should users do if they encounter installation errors while downloading FM WhatsApp?

If users encounter installation errors while downloading FM WhatsApp, they should first ensure that their device meets the app’s requirements and that the APK file is not corrupted. They should check if they have enabled installation from unknown sources in their device settings. Clearing the cache of the file manager or re-downloading the APK from a trusted source may also resolve the issue. If problems persist, seeking help from online forums or the support section of the download website might be necessary.
