The EI2012 Service Pack makes available for the first time a fully 64-bit application of EnviroInsite. We haven't formally benchmarked the application, but do expect it to make a significant difference with large files. You should be aware however that if you have the 32-bit version of Microsoft Office installed on your computer then you will be limited to the 32-bit version of EnviroInsite. This has been confusing to us as well as our clients, however it apparently has to do with some shared database engine files that both EnviroInsite and Microsoft Access both rely on.
