This is quite normal and safe for your PC. While working our software analyzes HTML-code of many sites (pages). This is possible that there are some harmful Javascript-invasions in the analyzed HTNL-code, which would infect your PC if you opened such a page through your web-browser. But as CS Yazzle does not runJavascript-code such an ability to infect your PC through our software is not possible.

This parameter shows middle-geometric value of distance (in symbols) between external links on the set page. We must remark that in this case only external links are counted and only those which have text-anchors of non-zero value. So, this parameter characterizes well-known "block-like" feature of links' placing. The higher its rate the more natural are external links placed on this page.

Yes, of course. CS Yazzle saves information in the XML format, packing an eventual XML-document by the standard algorithm of the ZLIB compression. Thus, in order to decompress a YAD-file, for example, in Php it is enough to use built-in function of "gzuncompress" (the "Zlib Compression Functions library"). After unpacking you will get the correct XML-document of the approximately following maintenance (through two slashes is brought our comments over, which in the real file are not present):

One license CS Yazzle assumes setting on two different computers due to the generation of two different registration codes. Thus, you are enough to acquire 1 license. Renewal (repeated generation) of any of the codes added to Your registration-account is possible not more frequent than once a month.

Additional tools (menu-item "Tools") are not accessible in a demo-version, and also the number of results of analysis is limited (5-6 positions). In addition, saving of results of analysis in the CSV, HTML, Excel formats is not supported (the direct export in Microsoft Excel works here).

You have to:

1. Sign in with your site's profile.
   
2. Download the full version of our software (if you are unathorized you will download demo-version that can not be activated). After authorization of the user with payed licenses links to a demo-version will become links to the full-version of the software (on the main page and in the "Download" section). Be attentive!
   
3. Install full version. When see a question about files' replacement say "yes" except YAZZLE.INI file.
   
4. Run the full version using shortcut on the "Desktop".
   
5. In the program's Menu item Help > Activate... you need to get authorization's code (it is unique for every separate PC).
   
6. Go to site's section "Management of licenses" (accessible only when you are signed-in). Put an authorization-code in the proper field and generate registration's code ("Generate and save" button).
   
7. Received registration-key you should enter in the activation-window of the program (the re was a code for authorization formed, look at (3)).
   
8. Restart the program. In case the activation was done in the main-window's heading the words "unactivated copy" will disappear.
