Installing Dr.Web

If you are using Microsoft Exchange Server 2013 with SP1, but without Cumulative Update 5, run the Exchange2013-KB2938053-Fixit script available on the Microsoft official website at https://support.microsoft.com/help/2938053/third-party-transport-agents-cannot-be-loaded-correctly-in-exchange-se before installation to prevent errors of registering the transport agents during the installation.

1.Run the installation file drweb-[version]-av-exchange-windows-x64.exe. The InstallShield Wizard will open on the first window of the installation process.

2.To continue installation, you should read and accept the terms of the License Agreement by selecting I accept the terms in the License Agreement.

To do so, click Open the list of services link, right-click the service in the list and then click Stop. Once the service is stopped, click Next.

Stopping Microsoft Exchange Transport service manually is required to preserve the installation integrity on the server operating under load.

In some cases Microsoft Exchange Transport service may take considerable time to stop.

4.Select the licensing type. You can register your license later, specify the path to the valid license key file or use the key file from the centralized protection server if Dr.Web Agent is installed on your computer. Click Next.

For correct plug-in operation, specify the path to the drweb32.key license key file.

To register license after installation or to renew it, copy the valid license key file to the program installation folder, then restart Dr.Web for MSP Scanning Service.

5.Before starting the installation procedure, click Installation parameters to configure the following parameters:

•Install transport agents—allows you to install transport agents (enabled by default). If you are using Microsoft Exchange Server 2007–2019, enabling this option registers the DRWTransportAgent.dll library and its transport agents (anti-virus and anti-spam) by Microsoft Exchange Transport service.

•Install VSAPI—allows you to install the DrWebVSAPI.dll component for scanning via VSAPI (not supported in Microsoft Exchange Server 2013 and later) provided by Microsoft Exchange Information Store service. If this option is enabled, you can also configure additional parameters: enable scanning of the outgoing messages, proactive and background scanning.

You can also enable the transport agents installation and registration monitoring by selecting the Enable transport agents monitoring option. During the installation on Microsoft Exchange Server, transport agents are registered in SMTP transport system by Exchange PowerShell, which does not close automatically, so you will need to enter the exit command manually to complete installation.

To avoid transport agents registration errors during the installation, please make sure that the RemoteExchange.ps1 script is installed on Microsoft Exchange Server (the script is located by default in the %PROGRAMFILES%\Microsoft\Exchange Server\V14\bin\ folder on Microsoft Exchange Server 2010 or in the %PROGRAMFILES%\Microsoft\Exchange Server\V15\bin\ folder on Microsoft Exchange Server 2013).

6.If you are re-installing the application, you may use the saved configuration (if the corresponding option was selected during its removal) or delete it and re-configure the application after installation. Click Next.

The installation of Dr.Web on your computer will start. By default, program files are copied to %PROGRAMFILES%\DrWeb for Exchange and %PROGRAMFILES%\Common Files\Doctor Web folders. the event logs and auxiliary files are copied to %PROGRAMDATA%\Doctor Web folder.

7.If you selected the Enable transport agents monitoring option when configuring thee installation parameters, you need to exit the monitoring window after the transport agents are installed and registered. The "Dr.Web AntiVirus Agent enabled" and "Dr.Web AntiSpam Agent enabled" messages in PowerShell indicate the successful agents registration by Microsoft Exchange Transport service. Enter the exit command in PowerShell.

The restart is not required: the Microsoft Exchange Transport service is started automatically, resulting the correct operation of the server. However, if the POP3 and IMAP4 supporting services are running on the server, restarting the Microsoft Exchange Transport service may disconnect them from the server transport system. In this case it is recommended that you wait until Microsoft Exchange Transport and the installed application services are started and then to restart the Microsoft Exchange POP3 and/or Microsoft Exchange IMAP4 services manually (or to restart the computer).

The application configuration file cmsdb is not deleted by default on deleting the application. Therefore, all user settings are saved and may be used after the next installation of the product. However, if you install a newer version that contains new basic configuration parameters, you cannot use the saved configuration file "as is", because it can lead to failures in the operation of application.

If you prefer to re-use the saved configuration parameters when updating the application to a version later than the next one, please contact Doctor Web technical support to inquire about the Dr.Web CMS parameters compatibility in different versions of the application. Generally, if the newer version contains additional parameters, it is sufficient to add the new variables to the existing configuration base and specify their types and default values correctly.

2.Delete the cmsdb and cmstracedb files from the %PROGRAMFILES%\DrWeb for Exchange folder manually.
