I installed x64. Everything works fine. Then I installed Visual Studio 2005 and MS Office Visio for Enterprise Architects, spec release for VS2005 I can make new visio drawing, can open old one, except Database Model Diagram! When I trying to open a new one, stencil is open for this type of drawing and... and visio is halted. The same happen opening an existing db model diagram. On XP 32bit no problem with this release of Visio. Could sy suggest me some resolution to avoid this problem? szabti
