Hi there,
I have a new dell inspiron i7 4GB Ram laptop - Windows 7

I have installed Vectorworks 12.0 and updated to 12.5.3 and its running fine. I would now like to install the latest itunes, but I'm worried, because in the past that has always caused vectorworks to crash because of the newer versions of quicktime.

Has that been resolved in the latest update? Can I safely install itunes, or is there anything I should do to prevent any issues?

I've searched previous posts but can't find anything recent on this.

Thanks in advance.

Anything aside from the version of QuickTime that shipped with Vectorworks is officially unsupported, unfortunately. You could perhaps experiment by creating a VM and trying it, but since QuickTime's APIs tend to change over time it's not surprising to see issues.
