I bought this a while back from ebay. It sounds like the same one I bought. You need to run open office to use it.
It is decent. Lots of added stuff as mentioned. Noticed the odd flaw with the certs though. Dunno if its changed now but on my version (bought back at the time 17th was coming in) you could select between 16th and 17th versions. However I noticed things like the schedule of items inspected were still written to the 16th on green periodics. As I think ive mentioned before im sure theres a way you could edit it but whenever I tried all I managed to do was bump stuff over onto another page leaving big gaps etc lol.
Anyway well worth the money just keep your eyes peeled for the odd error.
