Hi,
I developed an application that i compiled and run on 32 bit..but I wish to rum my application both 32 and 64 bit..can it is possible ..
when i change platform x64 from solution project property then it does not run on 32 bit and if i select any CPU then it run 32 bit but not 64 bit...
thanks

All 32 bit programs will run on a 64 bit system, but you can obviously only compile (as well as run) apps on a 64 bit platform.
If you can't have over 4gb in your pc, why write software that addresses 8gb?
Hi,
Your first point is confusing me because it’s not necessary that all 32 bit apps run on 64 bit and about your 2nd point my application have not any storage limitation
Just put target platform as any and it will run as 32-bit on 32-bit systems and as 64-bit on 64-bit system. .NET code is not a problem but take care to check all interop since you may have problems with it when porting.Quote:

Note that 64 bit processes tend to be bigger and run slower than their 32 bit counterparts. Consider that every reference takes twice as much memory (and therefore only half as many can possibly fit in the processor cache.
