Users rights to use the anti-virus are specified in the key file. The following information is contained in the key file:
| · | list of anti-virus components licensed to the user |
| · | product license validity period |
| · | other restrictions (i.e. the number of protected PCs, etc.) |
The key file has the key extension and must be located in the installation folder by default.
|
|
The key file has a write-protected format and must not be edited. Editing the key file makes it invalid. Therefore, it is not recommended to open your key file with a text editor which may accidentally corrupt it. |
There are two types of key files:
| · | License key file is purchased with the Dr.Web software and allows a user to use it and receive technical support. Parameters of the license key file are set in accordance with the software's license agreement. It also contains information about the user and seller. |
| · | Demo key file is used for evaluation of Dr.Web products. It is completely free, provides full functionality of the software but has a limited duration and cannot be renewed. |
The key file can be delivered as a .key file, an archive containing such file or a .dwz file used by the Automatic Updating Module to deliver packaged updates. A user can receive the key file in one of the following ways:
| · | Via the Dr.Web Updater after registration during installation or the first update. The utility registers the program (after providing the serial number) on the official web site and receives the key file. This procedure is available only for Dr.Web programs which protect individual workstations. Without a serial number the user can only receive a demo key file. |
| · | Via e-mail or by downloading it from the official registration page after providing the serial number supplied by the seller. Without a serial number the user can only receive a demo key file by filling out a form on the demo request page. |
| · | The key file can be included in the distribution kit of the program. |
| · | Via e-mail as an attachment with the .dwz extension. Double-click the attachment icon to install the key. |
| · | Via a separate data carrier provided by the seller. |
| · | Supplied as a zip archive containing a file with the .key extension. Extract the key file using the respective archiving tool (WinZip or Pkunzip) into the Dr.Web installation folder. |
It is recommended to keep the key file until it expires. If you re-install a product or install it on several computers, additional registration of the serial number will not be required because the key file received during the first registration can be used.
If a key file is lost, you should register again. In this case, input the personal data specified during the first registration procedure. Only the e-mail address may differ. The key file will be sent to the specified e-mail address.
The number of requests for a key file receipt is limited. One user cannot register a serial number more than 25 times. If more requests are sent, the key file will not be delivered. To receive the key file, contact our Technical support service (describe your problem in detail, state your personal data input during the registration and the serial number) and the key file will be sent to your e-mail address.

|
If no valid key file is found (license or demo), the functionality of the program is blocked. Users of Dr.Web products for workstations (including Dr.Web CC) can use only the Dr.Web Updater which lets you register the software and receive a key file for it. |
|
|
Beginning from version 4.33 the key files of Dr.Web for workstations and Dr.Web for servers differ. If you use the wrong key file, some components, such as SpIDer Guard for Windows will be disabled. |
