Everyone understands that you don't have a contractual obligation to deliver what you said was planned on the schedule that you provided, but your most recent posts imply that you no longer have any specific plans whatsoever to deliver a 64-bit compiler.
It appears that you say that you "want" to provide a 64-bit compiler but that you aren't investing any resources to get it done, that you don't have any specific plans to do so, but will think about it in the future. Is that the situation? It is just bad customer relations to say you're going to do something and then when you don't get it done be so vague about the new situation. At least communicate clearly.
I have email from Excelsior JET from mid-2006 that stated: "Excelsior plans to enable JET for creating 64-bit code during next year." Another, from late-2006 stated: "We plan to release a version with support for 64-bit AMD platform as well as with support of Vista in the next year (3-4Q 2007)." Then, in this thread in early 2008: "This time I'll be more definitive. The work has been started and we plan to release 64-bit version for Windows and Linux in 2009. We have invested lots of resources in preparing this port so the new version will match the maturity and overall quality of the 32-bit version. First beta will appear in 2Q 2009."
Virtually every new Windows machine is being sold with a 64-bit architecture and 64-bit OS. Even low-end machines are being sold with 4GB RAM. Yet, it appears Excelsior JET has no plans to provide a 64-bit compiler.
Unfortunately, my advice to those who have not yet developed solutions that would rely on a 64-bit compiler from Excelsior JET to consider alternative approaches. Even those of us who are current customers will need to consider redeveloping with other approaches.
