The antivirus complex from 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 for a long time about the disadvantages and advantages of Kaspersky, but one thing is clear - this anti-virus is one of the best. However, during its installation, some users encounter a problem when Kaspersky is not installed. In the best case, an error message is generated (by the code of which you can try to find out the reason), and in the worst case, the installer simply finishes its work. Obviously, many are asking: “Kaspersky is not installed, what should I do?”
Abundance of reasons
Despite the fact that many sources offer a solution to this problem, only in some cases it is possible to quickly figure it out. The reason for the failure when installing the antivirus on a particular hardware and software configuration is always individual and requires careful analysis. There is no universal answer to the question “why Kaspersky Anti-Virus is not installed”.
Therefore, our article provides a number of the most common causes of failure.
Compatibility
In the first place are compatibility issues. As you know, users' computers are currently actively using one of the four operating systems from Microsoft - XP, Win 7, Win 8 and the latest modification of "Windows" - Win 8.1. And any program, especially such a complex one as an antivirus, is characterized by requirements for the execution environment, i.e. operating system. For example, do not be surprised that Kaspersky is not installed if you try to install the version of 2012 on Win 8. Accordingly, 2013 works correctly with Eight, but it cannot work with the updated Win 8.1. In addition, most often “Kaspersky” is not installed even on Win XP, if the latter does not have the SP2 or higher service pack installed. The corollary of the foregoing 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.
Software conflicts
Although in some cases it is possible to install several anti-virus packages from various developers, this does not work for Kaspersky. If the installer detects the active code of another security product, the installation will be aborted, indicating the requirement to remove the duplicate program. In addition, sometimes “Kaspersky” is not installed due to the fact that the other version of the product before it was deleted incorrectly. In this case, you need to download the free kavremover program from the developer's site, with which you can completely remove the "remnants" that interfere with the installation.
Malicious code
Installation problems can occur on computers infected with certain viruses: some "malware" monitor installed applications and, upon detection, Kaspersky simply stops the installation process. In this case, a completely plausible message may be issued, which complicates the diagnosis and the search for the cause. Thus, if the system requirements correspond to the product, but the installation fails, you need to download the free Kaspersky VRT program and scan the computer. Alternatively, you can try installing an antivirus from another developer, cure the computer, and then install Kaspersky.
