This will save you some time because you won’t need to send a request to Technical Support (whose engineers would offer you the same solution to start with). Just consider it a remedy should you encounter errors while upgrading or reinstalling Kaspersky Lab products.
Most errors caused by registry leftovers are numbered (or may have no number at all), but there is no need to make a list of errors that are fixed by Kavremover. We call this utility magic because it eliminates almost all errors that are not caused by violation of system requirements - all you need is to download it and run it in the Safe mode. Having troubles installing #Kaspersky products? Use KAVremover tool ― it’s magically effective! Tweet With this option, you can remove all traces of Kaspersky Lab products from your computer, which works both for consumer applications and business solutions. As a matter of fact, it acts like the standard Windows tool in a normal mode, but when launched in the Safe mode, it uses its own removal algorithm. It is a small freeware application that “knows” all Kaspersky Lab products’ registry keys and successfully deletes them. To fight registry leftovers, you are welcome to use a special utility named Kavremover, which is supported by our developers. This will be a consequence of making unauthorized changes to the system, so whenever you decide to test such a utility, enjoy it responsibly. No matter how tempting it is to “optimize” Windows using third-party applications, please be aware you might end up reinstalling the system after a critical failure. As a result, application removal completes with errors and a new installation cannot be performed because of it.
Of course, sometimes you can make your system load a couple seconds faster by using them, but it often happens that tweakers delete links between our registry keys, so our removal algorithm cannot use them properly. This happens either when a previous version was uninstalled through Programs and Features or when a newer version was installed on top of the old one.Īnother reason why the leftovers remain in the system is the usage of tweakers like CCleaner.
Windows Installer may be unable to remove some drivers or registry keys. The original copies of Windows are not entirely flawless, though, and may malfunction in some way after a couple of years since the system was installed. As for the latter, no one knows for sure what changes to the original system are made by their authors. It’s very likely that you will face the problem if you have a system without Service Packs installed, or one of the custom “homemade” builds of Windows. If your Windows copy is damaged and works incorrectly, it may result in the malfunction of the Windows Installer service. Where do the leftovers come from? First of all, they may appear because of the operating system errors.
For those who speak literary English, we will paraphrase it as “system files and registry keys remaining after a previously installed Kaspersky Lab product had been removed.” If a previous version of a product was not uninstalled completely, you may be unable to install a newer version. Here in Kaspersky Lab Technical Support, we call it “leftovers”. We have already examined what happens when the system requirements are not observed, but there is another common reason why installation may fail.
