James,
Can you give some more detail? Are you installing it in a new location
or overwriting an existing location. Did you use the 2.6. or the 2.6.1
allinone download?

Jason,
I extracted in a folder from C drive like you said. I tried something too, I created a new report project with a blank report file and tried it, and it worked, I was able to create a chart without that issue. However when I check out our project code from SVN is it then when I am noticing this issue. It never had this problem with older versions of BERT (2.4 and 2.5). Me and another guy are using different older versions of BERT to build reports and both work fine just have issues opening each others reports to edit them, so that is why we are trying to just upgrade to the latest and be compatible. Might it have to do with the location of where I am creating the report file? Our current reports live within a Package with other java files.
One more thing I tried and noticed too was that it worked when I tried to add a chart to a report file in a new report project, and didnt work when I tried to add a chart to a report file within our code checked out from SVN.
Thanks again for your help.

James,
I am not exactly sure what you mean. When you create report inside your
project it fails?

Understood. Does you project have any dependencies set that reference
birt projects? Also does your report call any java classes?

Can you give some more detail on how you are using the engine?
If you are using BIRT in an RCP application there is no need to download
the runtime. If you are deploying BIRT to an app server you will need
the runtime.

Understood. Can you try to leave all the libs and create a separate
report project in the same workspace to create and modify your reports.

Lionel,
It would be good if you could log a bug for this.
If you create a separate report project you should be able to set its
classpath to the jars in your Java project in the preferences.

I do not think there has been a bug logged for this yet.
