GCC Compiler package for Macintosh

In order to run Simile models at full speed, you need a c++ compiler. Simile for Windows has one included in the distribution, while most Linux users will already have the GCC compiler suite on their system. Mac users fall somewhere in between; if they do not have a copy of GCC and cannot easily download it from the Apple Developer Connection website, they can download it here. - 43.5MB

Prolog executable for ARM Windows machines (no longer needed)

The previous Windows version of Simile fails to start on an ARM machine (e.g., Microsoft Surface) because the on-the-fly translation fails with the Prolog executable, xgsimile.exe. Here is an alternative version, 3.1MB, still x86 but 32-bit, which replaces that file (in Program files/Simile7.x/System64/bin) and gets it working. 

Simile 7.4 (free) for Windows includes a Prolog executable built for ARM processors and detects what system it is running on in order to execute the right one.

R package compatibility for Windows

Simile v7.4 binary download for Windows has been built with TclTk 9.0 for all the latest performance improvements and features. However, the R package is yet to catch up and still relies on TclTk 8.6. The answer of course is to compile your own Simile from GitHub, but the binary distribution can be made to work with R by replacing the files in System/lib/Stubs with those packaged here. Unfortunately it will then not work as a desktop application until the original .dlls are restored.
