Question

I wish to change the target CPU settings from “Any CPU” to “x86” in Visual Studio 2010.

I read on another website that I need to do the following:

1. Go to the startup project of your program.
2. Open the properties window.
3. Click the compile tab.
4. Click advanced compile options.
5. Change the target CPU options to x86.

But I don’t see the “compile” tab anywhere in the properties.

Please help me at the earliest.

Update: I do see a platform dropdown, but that contains nothing apart from “Any CPU”,

.

I believe the reason you don’t see the Compile tab in the project properties is because you’re using the Express edition. Optimization for a specific CPU type is not offically supported in this edition. However, you should be able to change the active solution platform in the following way:

From the “Tools” menu, select the “Options” item, and then select the “Projects and Solutions” option in the listbox on the left-hand side of the Options dialog. (You might have to check “Show all settings” first.) Check the box that says “Show advanced build configurations”:

Then, on the “Build” menu, see if you have an item called “Configuration Manager”. If not, you need to add the item to the menu (right-click on any area in the toolbar and choose “Customize” at the bottom of the list).

Once you’ve opened the Configuration Manager dialog, go to the “Active solution platform” drop-down box and choose “New”. From the “New Solution Platform” dialog that appears, you should be able to choose “x86” from the first drop-down box.

Alternatively, it looks like you can manually edit the project file to specify the CPU type. See Changing the target CPU in VB Express 2008. It looks like it amounts to simply changing the <PlatformTarget> under the first <PropertyGroup> section to “x86”.
