John

You have to change the insides of the EXE (program code). That is about the only way you can do this.

You mean to say that we have to upgrade our application from 32 to 64-Bit then it will use use the memory beyond 2 GB.

John

Yes, you must upgrade to a 64-bit application to use more memory. That is what I noted above about Excel as an example.

Thanks Klahn,

any idea about compilation of application with "IMAGE_FILE_LARGE_ADDRESS_AWARE option?

Dr. Klahn

That's correct. The only way to get more than 2 GB to a 32-bit application is to use 32-bit Windows in a non-standard configuration and recompile the program. Unless you have the program source recompilation is not an option -- and you would still be stuck with a 3 GB limit.

If you do have the source then you should recompile the program as a 64-bit application. Then it can run in native mode on a 64-bit system and use significantly more memory.
