This question came from our site for professional and enthusiast programmers.

Try copying c:\Windows\System32\calc.exe from a Windows 7 machine to a Windows XP machine and see if it runs? – Blorgbeard Apr 7 '11 at 12:10
@Blorgbeard - it doesn't. Calc.exe returns an error message – stevenvh Nov 13 '11 at 9:45

Sometimes the easiest answer to a Microsoft question is actually Microsoft themselves. Within their Download Free Tools Section you will find something which is called "Microsoft Calculator Plus". It has been available for at least 8 years. I have used it for a long time in XP and Vista. Amazingly albeit MS had it available they never integrated it into their OS installation Disks for Windows XP SR3 or any of the Vista Versions, neither was it integrated into any of their Service Release Updates. Strange, I have no idea why since it looks the same but includes mathematical and conversion functions. The only issue with it is that it installs with an odd looking interface. But you can change it to the classic style in the menu. What a relief.

Yeah, the default theme freaked me out, I've never seen anything that ugly before! @gsgoodguy: The classic theme looks exactly like the calc.exe you're used to from XP. – Jonas Byström Feb 5 '14 at 10:28

It probably isn't possible, certainly isn't supported and may well be in violation of the license agreement for Windows (although you may want to have that reviewed by a lawyer to be sure). Copying the binary might work, but it is unlikely since the calculator is part of windows so they have no need to make it run on downlevel versions.

Running the W7 version of calc in XP will get you an error of "not a valid win32 application", compatibility mode will not help.

Taken from here

As you all know there are lots of user who have already introduced Windows 7 calculator for XP, but using Windows 7 calculator in XP requires Microsoft.Net Framework. Here I am Re-introducing a new version of Windows 7 calculator for XP which don’t required any Microsoft.Net Framework.

This calculator Mod has been developed by Mr. Harsh Shivhare. You can install or use it in Windows XP SP2 – SP3, either replace Calc.exe in System32 folder or just click on calc.exe to run it.

You can download it from following link:

Or you could:

And for Windows XP’s users, you too can have the Windows 7 Calculator on your machine. This XP version of Windows 7 Calculator has the similar interface as the original one but it can only work for standard mode. It is very sad that you can’t try the two newly added modes, Programmer and Statistics. Installation is not needed to use this calculator. Just extract the downloaded zip file and run the calc.exe file. You need Microsoft .NET framework 3.5 on your Windows in order to run the application.

Alternatively in Vista:

Download Windows-7-Calculator.rar.

Virus report-clean-1hit

Unpack the content to another folder, and run the calc.exe to use the Windows 7 Calculator in Windows Vista. To replace existing default Calculator program in Windows Vista, copy calc.exe to \Windows\System32\, and calc.exe.mui (in en-US folder) to \Windows\System32\en-US\ folder, overwriting existing file (you may want to backup the old Calculator binaries first in case of error running Windows 7 version). Voila, now the new Windows 7 Calculator has been installed on Windows Vista.

Neither of these let you run Windows 7's calculator on an XP machine, as OP asked. – stevenvh Nov 13 '11 at 9:47

Calculator Plus was already mentioned above, but Microsoft also offers another advanced calculator for download on their site which has more functions and graphing calculator abilities: Microsoft Mathematics 4.0
