Depending on the reason, you may use the appropriate method below to resolve your issue.
- Reinstall the application that is causing the npptools.dll error
At times, npptools.dll error messages appear only when you try to use a particular application. If this is the case, then promptly uninstall and then reinstall this application. Reinstalling the application will replace the missing or damaged npptools.dll files as the installation setup files of any program contain all the files that are essential for the application to work properly.To ensure complete removal of the software during uninstallation, you may use a reliable third-party program uninstaller tool, such as Perfect Uninstaller.
Similarly, if you receive an npptools.dll error after you have uninstalled any program or application from your PC, reinstall the program to correct the error. You may have removed the npptools.dll file during uninstallation, causing missing npptools.dll error messages to appear. Reinstallation should replace this missing file.
Additionally, care should be taken when you install or uninstall an application or program from your system. While installing a new program, ensure that you do not overwrite a current version of a shared DLL file with a previous version. Similarly, while removing an application do not delete any shared DLL files.
- Use the System Restore function to undo any recent system changes
If you encounter the error as a result of any recent changes that you have made to the registry or any important system file, you may use the System Restore utility to fix the problem. This tool rolls back your system to its previous working state by undoing the recent changes you incorporated.
- Keep your operating system updated with the latest service releases
Many DLL errors occur due to outdated files. To prevent this, it is important that you keep your operating system, software and device drivers up-do-date with the latest service packs, hotfixes, patches and security releases that are periodically released by the manufacturers of these products.
- Keep your system protected from malware infections
Malicious programs, such as virus, Trojan, worm, adware, and spyware often edit or remove DLL files present on your system, causing DLL error messages to appear on your screen. That is why it is important that you regularly run full system scans using reliable virus and spyware scanner tools, such as STOPzilla Antivirus and Spyware Cease, to ensure that your system is protected from malware infiltrations.
- Keep your registry clean and healthy
Registry problems may also cause various DLL errors. This happens when the entries related to DLL files in the registry are corrupt or invalid. You can easily ensure that invalid, obsolete and corrupt entries are absent from your registry with the help of an advanced registry cleaning tool, such as RegServe. This tool allows you to deeply scan the registry and remove all the corrupt entries with just a few mouse clicks.
