Here is a link to our current
software compatibility list; this is the place to always find the most current information. To summarize and answer the questions in this thread, as of this posting date 7/11/2011:
- SI5.5 SP3 is compatible on 64-bit operating systems, it installs as a 32-bit application in the C:\Program Files (x86) directory
- SI5.5 is
NOT compatible with 64-bit versions of Visio or AutoCAD, you must be running the 32-bit versions
- If you install the 64-bit version of MS Office, you will not have Outlook compatibility. Also, you will not be able to install the 32-bit version of Visio on a machine running the 64-bit version of MS Office.
- If you are running a 64-bit OS, the AutoCAD 2010-2012 installers will automatically install the 64-bit version. The only work-around that we know of to get the 32-bit version of AutoCAD to install on a 64-bit machine is
explained here.
