System requirements for older versions
Older versions of SIMetrix will run on the operating systems supported at the time of their release. In general, we have found that all 32-bit Windows® versions of SIMetrix back to version 1.0 will usually run on any 32-bit Windows® operating system, but often need special install procedures. However, we have not tested every version of SIMetrix with every version of Windows® and can make no guarantees or offer any support for non-supported operating systems.
There can be problems with older versions running on 64-bit systems. In particular versions 5.3 or earlier using portable licenses (i.e. with a USB security key) will not work with any 64-bit system.
