A-Track for Windows

Important : If you are using Norton security programs on your computer, you may find that files downloaded from this page are erroneously flagged as a threat, or even quarantined, possibly with the threat classified as "WS.Reputation1". This does NOT mean that the files are infected with any form of virus or other malicious software, but simply that the files are new to the Internet, and have not been downloaded by many people so far. Previously you could verify this on the Symantec website at http://www.symantec.com/security_response/writeup.jsp?docid=2010-051308-1854-99, but this article has been removed following Symantec's takeover by Broadcom. There is a similar explanation on the Norton website at https://community.norton.com/en/forums/clarification-wsreputation1-detection or you can use Google or another search engine to check on the meaning of "WS.Reputation1".

Unfortunately, as a very small software developer, A-Train Systems has no influence with Symantec to change this behaviour, but can only assure you that no files here contain malware nor pose any kind of danger to your computer. This also applies with some other Internet security suites and types of browser, which may display warnings when you try to download the A-Track Setup executable file, in particular, or even block the transfer. In case of continued difficulty, please use the Contact form to request further assistance.

All of the A-Track documentation has been completely updated to cover the new program features incorporated in Version 4.4.3. Since the updated Reference Manual now stretches to over 500 pages, you may wish to start with the much shorter User Guide which, after a summary of the main features, covers program installation together with a brief description of all functions accessible from the main menus. Note that the full text of all sections of the Reference Manual are available from within A-Track as context-sensitive Help pages. Pressing the F1 key at any time when running A-Track will open a Help page directly relevant to whichever program function you are currently using.

Following re-hosting to a new server on 09 February, and a change in how file security is handled, the Check for Updates facility in previous versions of A-Track will no longer work.

All users are, therefore, recommended to update to the latest version - Release 4.4.325 - which can be obtained via the links below.
