Thinking about that new 64 bit OS/Machine for AutoCAD Architecture? Before you go shopping check out this comment from Jason (copied from this post, also posted to an ACA Discussion Group thread):
“My firm has been using ADT 2007 (and the previous releases) on Windows XP x64 in a production environment for nearly 2 years. The only caveat was to make sure that the 64 bit version of the .net 2.0 package was installed and that the "support file search path" pointed to 'C:\Program Files (x86)\Autodesk Architectural Desktop 2007...' due to the way that XP x64 segregates the 32-bit native programs from the 64-bit native ones. Autodesk has never supported the install of ADT on 64-bit OS's. But they allowed the programs to install.
In ACA2008, they have programmed the .msi installer to abort on the detection of a 64-bit OS. Chris Yanchar's response is that they are not supporting ACA2008, hence the installation limitation. My contention is that Autodesk should include this functionality in the current release (ACA2008) as they did in previous releases.”
I’m not running 64 bit, or even Vista, yet so hadn’t encountered this limitation. Strangely the ACA System requirements published on the website only state XP/Vista and there is no mention of 32/64 bit at all, even in the linked FAQ PDF.
Autodesk - AutoCAD Architecture - Features & Specifications
Recommended System Requirements
- Intel® Pentium® 4 or AMD Athlon™ processor, 3 GHz or greater
- Microsoft® Windows® XP (SP2 or later) or Vista™ operating system
- 3 GB RAM
- 3.1 GB free disk space
- 1280x1024 monitor and display adapter capable of 32-bit color
128 MB or greater, OpenGL®-capable workstation-class graphics card- MS Mouse—compliant pointing device
- Microsoft Internet Explorer 6.0 (SP1 or later)
- The preceding requirements are recommended for effective use of AutoCAD Architecture.
I assume it also applies to AutoCAD MEP? If AutoCAD Architecture/MEP will not install on a 64 bit OS it should be clearly stated.
