Kaspersky Antivirus and Internet Security products have generally suffered from an error during the configuration process that prevents the installation and requests a restart to continue. After rebooting, the problem persists:
The installation stopped prematurely because of an error. “
Although this is not as widespread as a few years ago, people still encounter the error and it is obviously important to ensure that your paid protection works. We present here a selection of solutions that we found to work around this error and allow your Kaspersky product to continue its installation. This applies to all versions of Kaspersky Internet Security and Antivirus and possibly PURE.
1. A Leftover Registry Key
It is possible to create a registry key when uninstalling an older version of Kaspersky. For some reason, this key is left after a reboot. You must delete a key called avp ** _ post_uninstall from your registry. ** is a version number of Kaspersky that never deleted the key. Just follow the simple steps below to remove the registry key.
- Hold down the Win + R keys or go to Start -> Run, type regedit and click OK.
- Go to: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Run
- Expand Run and look for a registry key avp ** _ post_uninstall. For example, you can find one called avp12_post_uninstall.
- Right-click the key with ** _ post_uninstall and select Delete.
- Now try installing the Kaspersky product normally and hope that the error message is gone during the installation. This is a quick and easy solution that deserves to be checked, even if you are not already installed Kaspersky. Note that this registry key does not appear in most startup tuning tools such as CCleaner or Glary Utilities and must be checked manually.
2. Traces of a Previous Security Package
One of the most common causes of the “Installation ended prematurely because of an error” message is that the Kaspersky installation detected traces of another security package that was blocking and interrupting the installation . Although Kaspersky products have recently detected these problems much better, they can still cause the installation process to fail. If you know the security package or packages that you installed before It is quite easy to use a removal tool to erase the remains of a previous antivirus package if you know what has been installed. Download and run the tool for each brand you have installed on your computer. It also includes previous versions of a Kaspersky product.
We have a complete list of 26 uninstallers and removal tools for Internet Security and antivirus software where you can download and run individual removal tools. Kaspersky also has its own web page containing antivirus removal tools with similar tools and recommendations. If you do not know what was installed before If you do not know which security software has already been installed, you obviously can not download and run a specific removal tool.
Fortunately, a program called AppRemover is able to detect and delete data left by many security applications, including the most popular Norton, McAfee, Bitdefender, Eset, AVG, Avira, Avast and of course Kaspersky. Download and run the AppRemover executable file and wait for the results of the system scan. If remnants of security software are detected, you will have the option to select them to remove them. After a reboot, you can try to install your Kaspersky product again.
3. Other Security Software Causing a Conflict
Although Kaspersky’s products now better detect currently installed and incompatible software, problems may still occur for lesser-known software and cause the installation to fail. Other third-party products have also been omitted or mis-detected. Comodo Firewall is known to cause problems with Kaspersky Antivirus because it can be detected as Comodo Internet Security, which includes the antivirus component.
Another antivirus, firewall, antimalware or antispyware currently installed can also be a problem. The best solution is to completely uninstall any other security software you may have on the system and to reinstall Kaspersky. Optionally, use the dedicated removal tool from solution # 2. Then, if all goes well and Kaspersky installs properly, reinstall the other software.
