we can't build a project in 64 bits with Visual Studio 2005 c++

Hi,
We are a team of 5 persons, one person of the team have configurated the code of us project and now in your machine he can build this project in 64 bits.

He has given the code to us. The problem is that we can't build the solution:
We open the project, we choose the platform x64 and configuration Debug, when us try to build the project, visal studio skip all the projects of the solution (and in configuration manager we see all the projects are selected), we see this message in the out window:

"Project not selected to build for this solution configuration"

If we try to see the properties of one project we get this message error:

"The operation could not be completed."

What is the problem? We need install something to build the solution in us machine?

Can any help me please? Thanks.

Are you running VS in 64-bit environment?

Hi, thanks for the reply.
We have a SO in 32 bits but the person that can build the solution also have a SO in 32 bits(after he try the application in a SO in 64 bits).

What could be the problem?

Can any help me please?

Thanks.

You cannot build 64-bit application on 32-bit platform. Change all settings to 32-bit.

Hi, thanks for the reply.

I don't understand this, why some persons of us team can build the solution with platform in 64 bits and the rest of the team can't build with platform in 64 bits?

Thanks.

Am I missing something from your problem description?
Again:
You can run and build 32-bit application on 64-bit operating system.
It is impossible the other way around. You will not be able to build 64-bit application on 32-bit operating system nor will you be able to run 64-bit application on 32-bit OS.

I tell you again:

One person of my team can build 64 bit application on 32- bit operating system, and the others can't build this application. Then he run the application in one machine with 64 bit OS.

Thanks for the replies.

To build 64 bit application with Visual Studio, both on 32 and 64 bit computer, it is necessary to install 64 bit compiler. Run Visual Studio installation, select Add - Remove Features. On the features selection Wizard step open VC++ node and select everything related to 64 bit development.

Thanks for the reply, I have tried this and now we can build the application on 64 bits. The persons that could not build the application had installed the default installation of VS and the other person, had installed the full installation of VS.

Thanks for all the replies.

The VS 2005 installer is flaky and buggy as hell when it comes to installing the 64-bit runtimes. Even if you have it checked,
it still gets broken if you don't have some other items checked. I would suggest doing a full installation from the start.
Check everything. If it works, you will see x64 listed in the platform pull-down box. Otherwise only Win32 will be listed.
