The anti-virus complex from the Kaspersky Lab is known to many computer owners. This program quite deservedly occupies one of the leading positions in reviews comparing the effectiveness of protection against "malware".
One can talk for a long time 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 encounter a problem when Kaspersky is not installed. At best, an error message is displayed (by the code of which you can try to find out the reason), and at worst, the installer simply exits. Obviously, many are wondering: “Kaspersky is not installed, what should I do?”
An 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 cause of a failure when installing an 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 lists some of the most common causes of failure.
Compatibility
Compatibility issues come first. 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 2012 version on Win 8. Accordingly, 2013 functions properly with the G8, but 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 and higher update package installed. The consequence of all of the above is the following: before installation, you need to familiarize yourself with the system requirements of the desired version and compare them with those already used on this computer.
Program conflicts
Although in some cases it is possible to install several anti-virus packages from different developers, this does not work with Kaspersky. If the installer detects the active code of another security product, the installation will be interrupted with a request to remove the duplicate program. In addition, sometimes Kaspersky is not installed due to the fact that thebefore that, another version of the product was uninstalled incorrectly. In this case, you need to download the free kavremover program from the developer's website, 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" monitors installed applications and, if Kaspersky is detected, simply stops the installation process. In this case, a completely plausible message may be issued, which makes it difficult to diagnose and find the cause. Thus, if the system requirements match the product, but the installation fails, you need to download the free Kaspersky VRT program and scan your computer. Alternatively, you can try installing an antivirus from another developer, disinfect your computer, and then install Kaspersky.
