Why is not Kaspersky installed?

Antivirus complex from the Kaspersky Lab is known to many computer owners. This program quite deservedly takes one of the leading positions in reviews comparing the effectiveness of protection against "malware". You can talk a lot about the disadvantages and advantages of Kaspersky, but one thing is clear - this antivirus is one of the best. However, when installing it, some users are faced with a problem when Kaspersky is not installed. At best, an error message is given (by the code of which you can try to find out the reason), and at worst the installer simply completes its work. Obviously, many are asking the question: "Kaspersky does not install what to do?"

Abundance of causes

Despite the fact that many sources offer a solution to this problem, only in some cases it is possible to quickly understand. The reason for the failure to install the antivirus on any given firmware configuration is always individual and requires careful analysis. A universal answer to the question "why is not installed Kaspersky Anti-Virus" does not exist. Therefore, our article lists a number of the most common causes of failure.

Compatibility

In the first place there are problems with compatibility. As you know, users' computers currently actively use one of four operating systems from Microsoft - XP, Win 7, Win 8 and the latest modification of the "Window" - Win 8.1. And any program, especially such complex as an antivirus, is characterized by requirements to the execution environment, i.e. Operating system. For example, do not be surprised that Kaspersky does not install if you try to install the version of "2012" on Win 8. Accordingly, the "2013" works fine with the "Eight", but can not work with the updated Win 8.1. In addition, most often, "Kaspersky" is not installed even on Win XP, if the latter is not installed with an update package SP2 and higher. The consequence of all of the above is the following: before installation, you must familiarize yourself with the system requirements of the desired version and compare them with those already used on this computer.

Conflicts of programs

Although in some cases it is possible to install several anti-virus packages from different developers, this does not work against Kaspersky. If the installer detects the active code of another security product, the installation will be interrupted with the requirement to remove the duplicate program. In addition, sometimes "Kaspersky" is not installed due to the fact that the previous version of the product was removed incorrectly. In this case, you need to download from the developer's site a free kavremover program, with which you can completely remove the "remnants" that interfere with the installation.

Malicious code

Installation problems can occur on infected computers that are infected with certain viruses: some malware tracks the installed applications and upon detection of Kaspersky simply stops the installation process. At the same time, a believable message can be produced, which makes it difficult to diagnose and find the cause. Thus, if the system requirements correspond to the product, but the installation does not work, you must download the free Kaspersky VRT program and scan the computer. Alternatively, you can try to install the antivirus from another developer, disinfect the computer, and then install Kaspersky.
