>>I usually install both compilers, so have not seen this issue. It seems something can be improved.

Unfortunately on 32-bit Windows XPs ( Professional and Home Editions ) only 32-bit Intel C++ compilers versions 8.1 and 12.1 are installed.

>>Would you please send a screen capture if it's convinient?

Yes and please take a look:

As soon as a developer presses OK button an error message Error: Cancelled is displayed in Output Window of Visual Studio.

Unfortunately, when 32-bit and 64-bit platforms for a project unselected in the Batch Build a 64-bit version of Intel C++ compiler invoked anyway. So, it doesn't solve the problem and a developer should monitor the build process.

Hi Jennifer,

>>...do you get the same error when you do batch-build for Itanium config?

No and I need to verify.

>>Could you try ?

Do you mean when a Linker option Target Machine is set to Itanium ( IA64 )? I'll try it and let you know.

I'd like to provide some additional technical information and I hope that it will help. So, a software engineer who will investigate the problem should look for the following piece of code ( or something like this ):
...
MessageBox( NULL, _T("Intel(R) C++ Compiler for Intel(R) 64 is not installed"), _T("File finding"), MB_ICONWARNING | MB_OK );
...
As you can see I've bolded a first argument ( NULL ) of the function MessageBox. The NULL means, that the window with the message won't have an owner and this is what MSDN says:

...Handle to the owner window of the message box to be created. If this parameter is NULL, the message box has no owner window...

So, ideally it should look like:
...
MessageBox( GetActiveWindow(), _T("Intel(R) C++ Compiler for Intel(R) 64 is not installed"), _T("File finding"), MB_ICONWARNING | MB_OK );
...
and in that case the owner of the window with the message will be Visual Studio. However, as I've mentioned in my 1st post, a simple message to the Output Window without a call to MessageBox function is an ideal solution.

Verified and I don't have a configuration for Itanium platform.

Verified and the same message is displayed.

Note: Here is a screenshot of available configurations:
