Difficulty Including Crystal XI R2 in installer

Hello

I am trying to include Crystal XI R2 SP5 Merge modules in my Installshield 2009 project.

I have tried the Installshield forum with no joy.

I add the merge module CR115_Net_2005 ( I am using Vb.net 2005) then build the project. When I try to install the resulting exe file , I get a message saying Error 2705.Invalid table: Directory, Could not be linked as a tree.

If I take the merge module out the problem disappears.

Has anyone had this and solved it before.

I have looked at the Directory Tables before and after and they look exactly the same.

Thanks
