A-Track for Windows - Previous Downloads

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.

Website Re-Hosting - Following the transfer of this website to a new server on 9 February 2021, the Help Menu / Check for Updates feature in those releases below which have it, will no longer work, and may hang indefinitely if used. To avoid problems, set the Check for Updates frequency to "Never".

Note that, in all versions, 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.
