I heard that build 9344 was available yesterday and selected Check for updates from the help menu, but after PD connected to the parallels web site, it returned a message saying I had the latest version of the software. I have build 9310. So apparently the checker is not working or they have not posted the latest build so that the checker sees it. The note about build 9344 elsewhere in this forum said use the update process from the Help menu or download from the web site. If you do the latter which I did, it asks for your name and e-mail address so it can send a new trial activation code which I don't need. I'm going to install the version I just downloaded and hope it sees my original license, but it's clear to me that Parallels needs to work out the bugs in their updating process. Seems like every time I update, there are always issues. Most software updating is much easier.
