After installing Quickr I wanted to check for updates on the IBM Fix Central website.
The check for the correct fix the site requested whether I was using version 188.8.131.52 or 184.108.40.206.
To check this I looked for the file C:\IBM\Quickr\PortalServer\version\TS.product which is an xml file - Wordpad should be ok to read it.
The installed version was listed as "220.127.116.11"
Easy when you know how :-)
