I am having a hard time in installing ACA2008 onto vista windows OP SYS; the installation is smooth till I run ACA2008 and find out that @ properties palette the style does not appear and all objects re walls, mass elements are specified as AEC_WALL or AEC_MASS _ELEM with NO indications to style.
Moreover, in the PROPERTIES palette, the DESIGN subfolder is minimized to "General" and "3d Visualization" tabs the rest is either shaded or nonexistent.
Keep in mind that walls&mass elements are usually set as WALL and MASS ELEMENT in PROPERTIES palette and the Tabs in each are much more in subdivisions.
I'd appreciate any help to resolve this problem.
