Hello,

I am in the process of porting our RCP application from 3.5 to Helios 3.6. During my port I discovered that the P2 API has changed significantly and I modified my headless update code to take advantage of the new API along with the UpdateOperation class. I found that updating from a version of our application that is using 3.5 to a version that is using 3.6 works perfectly fine however once I attempt to upgrade once more to another higher version of our application that is using 3.6 I get the following status error report.

Note that if I start with the version that contains 3.6 already I can update to my hearts content. It seems as if p2 is trying to do an install instead of a update. I have attched my update class code below. Is there any additional information I can provide that may be of use in assisting me with resolving this issue?

Best Regards,
Mike
