Unable to install SolidWorks 2012 SP02 (student edition)

Hi,

Yesterday I've tried to install SW 2012 SP02 on my computer. I had SW 2011 and during installation I was given the option to upgrade 2011 to 2012. I chose this option, but it gave an error.

Today I retried it, but got the same error: "Internal error: The Windows Installer for this product component did not run as expected: 1903."

It's a general error I guess, since I've seen several of them with different solutions. I couldn't find an e-mailadress, so that's why I'm asking in here before trying suggested solutions like editing the registry

I've added both logs. The one from today is the 2nd log.

I hope someone can tell me what to do.

Thanks in advance!

Onno
