How to get an add-on installer for unix and linuk ver5.2.3

[TomohikoHoshino]

I want to get below installer.
splunk-add-on-for-unix-and-linux_523.tgz

It seems same add-on with below URL because the downloaded file name for ver 8.3.0/8.3.1 is  similar with above an add-on installer name what I want.
https://splunkbase.splunk.com/app/833/

I also checked release history. But I was not able to find the way of getting past add-on files. Maybe install file for 5.2.3 is too old and Splunk won't support..

If there is the way of get pas released install file, please share me..

Thank you!

Try web.archive.org.  Even if you find it, however, it may not work properly with newer versions of Splunk and definitely won't be supported.
