h1. FAQ

h2. Why am I getting different warning messages for standard and advanced solvers?

Since the standard and advanced solvers use different algorithms, the results may be slightly different for the two solvers. This difference is primarily due to numerical reasons, which may be affected, for example, by the order in which the equation are solved. Because of this, if the numerical problems are in the vicinity of the threshold of being detected, they can be reported only by one solver.

h2. Can I run models stored on the network, instead of locally?

See [kb:Running models stored on the network] page.

h2. Is there a separate installation of SAP2000 for 32-bit and 64-bit machines?

*Extended Question:* Since there is only one installation file, does the installer install 32-bit or 64-bit version based on the computer properties, or does a single installation handles both types of machines?

*Reply:* The single installer installs both analysis engines on every computer. The decision of which one to call is made at the time of running the analysis and is based on the operating system and the user options chosen.
