64-bit os

can i use my 32 bit soft in 64 bit os

The answer is yes. 98.5% 32bit software should work without any problem if you have an amd64 processor (includes Intel Core 2 Duo, Quad and Core i3/i5/i7).

But don't expect old 16bit DOS applications like Turbo C++ to work in Windows 7 64bit.

Which processor do you have anyways?

 

[coderunknown]

some softwares have their own 32bit as well as 64bit version. so its advised to check once before trying any software. 1 good example is Winrar.

well i have i5 750

@ico But Adobe photoshop CS2 32 bit hangs in 64 Bit OS but Adobe Photoshop CS5 64 Bit does not hang!

It is the time to move on from 32bit. You've named a very heavy software.

amd64 or x86-64 processors are backwards compatible with the x86 instruction set, so running most 32bit applications shouldn't be a problem.

Yes. They just support 4GB ram and nowdays games recommended requirement is 4gb. also I heard that they have some problems with hard disks larger than 2.19Tb. Well that requires the mobo that supports them too but still OS is also a bottleneck.

corrected your typo. also nowadays all processors & motherboard support 64bit OS.

Thanks. Do you know about this 2.19Tb limitation for HDDs. Read it on Digit mag and understood most of it but not completely.

Dont you get the catch? 64 bit can use more than 4 GB RAM.

CS5 64 Bit it is optimised to use 64 bits. Cs2 32 is 32 bit.


Hence, 64 bit optimised s/w perform better in 64 bit OS.

can i use my 32 bit soft in 64 bit os

yes its usable in x64 platform but the reverse is not possible
Even I had the same doubt when i was about to switch to x64 platform
