A couple of folks wanted to evaluate the IntelliGantt Add In for MS Project recently and ran across an issue I would like to share. They had MS Project versions 2000 and 2003 respectively. Since the IntelliGantt Add In is built for MS Project 2007, they went to Microsoft and installed the MS Project 2007 trial version. After all, they wanted to see if everything worked before upgrading to MS Project 2007 and IntelliGantt.
However, in trial mode, there was odd behavior in that every time they attempted to 'Share' a project to their SharePoint site, MS Project thought it was in edit mode and therefore the 'Share' operation was not successful. Folks were able to export the project to SharePoint, but then were not able to 'Stay Connected' (which is basically how 'Share' works under the covers).
Being in the IT department, our intrepid IntelliGantt evaluators were able to activate their MS Project trial and then, lo and behold, the problem went away and full IntelliGantt sharing was available.
So, if you're testing IntelliGantt with a trial version of MS Project and are seeing this behavior, see if you can try IntelliGantt with a licensed version of MS Project during your evaluation.
Or you can just trust me :)
