HP SIM 5.2 with SP1

[IT QA]

I currently have HP SIM 5.2 and need to upgrade to the latest HP SIM.

What is the best approach or documents to find

I also get HTTP 400 error messages when attempting to link HP SIM via IE.
This is intermittent, any settings to look at or updates to eradicate this eratic behaviour

For info the best place to start is www.hp.com/go/hpsim.
See the link to Downloads, if you pull down the HPSIM 5.2 SP1 download you can use that to upgrade.
Also see the link to the reference library, there's lots of good info there. The technical guide is well worth the effort of downloading and keeping handy for reference.
