Build 2.9.0.75 of xlsgen re-includes the native 64-bit build of xlsgen.

Even though our isolated server is a perfect solution for 64-bit scenarios, there is still sometimes a need for the native 64-bit version of our core dll engine.

This build provides the files in question in the /x64 folder of the install. To use the 64-bit build, simply replace the files in question in your install.

Why the native 64-bit build is worth having?

1) Runs direct, not through the WOW64 layer, which improves speed
2) The dll needs not marshall method calls back and forth, unlike our isolated server, which improves speed
3) The dll allows effective use of the 64-bit memory bandwidth, a big difference with the 2GB limit of the 32-bit world
4) More convenient activation (than the isolated server), results in easier deployments as well

Of course the 64-bit build has limits as well, which are the limits of xlsgen dependencies (not xlsgen itself) :
1) Chart rendering unavailable since Microsoft OWC components do not exist for 64-bit
2) ODBC data source querying unavailable since there is no 64-bit version of this either
