If you have packaged a installer with your own packaged project with Visual Studio, and generated the. msi and setup.exe installation files, and selected the Visual C + + 2010 Runtime (x86) in the Project installation Prerequisites environment, Then you will find that, click Setup.exe installation, if you click the Setup.exe installation files again, you will need to install the C + + operating environment again, as if each time can not be installed by C + + prerequisite conditions.


The reason is that Microsoft's C + + operating environment product code has been changed.

The solution is as follows

Change the inside product to
