Are there any issues with respect to running Vensim DSS
in a 64 bit system after having a bunch of work done ( models , input files , output files, external functions )
in a 32 bit system ?

Does all previous work transition smoothly with exception of the need to re-compile external functions ?

Vensim runs fine in x32 and x64.

There is no need to recompile external function libraries, the Vensim executable is 32 bit, it can only load 32 bit libraries.

I'm in the final stages of a x64 version of Vensim. This one would need a new x64 build of any external function libraries.

Thank you Admin
