WIX Installer error during the build

Question

I try to learn how to do an installer with WIX on Visual Studio 2012, First I create an HelloWorld Project to test WIX and to do an easy configuration. But I have an error during the building : It says me :

"Failed to open the database. During validation, this most commonly happens when attempting to open a database using an unsupported code page or a file that is not a valid Windows Installer database. Please use a different code page in Module/@Codepage, Package/@SummaryCodepage, Product/@Codepage, or WixLocalization/@Codepage; or make sure you provide the path to a valid Windows Installer database. light.exe 0 1 SetupProject1"

I see several solution like change XML's encoding, switch utf-8 by utf-16. And I also try to delete the encoding statement. But it changes nothing.

Here is my WIX XML :

    <?xml version="1.0" encoding="utf-8"?>

      </Component>
    </ComponentGroup>
  </Fragment>
</Wix>

I also check "CodePage" and "SummaryCodePage" but I've not resolve the build problem.

I've tried that too : WiX ICE validation errors

Have you some Idea to fix it ?

Answer 1

In the database validation step, light.exe tries to reopen the MSI file for read/write access While anti virus scanning the new msi file that been created.

Try to do the following:

1. Exclude the temporary directory from the real-time virus scan.
2. Adding English input language in Windows' regional settings.
3. Disable the ICE validation. Go to the wix Project Properties, Tool Settings, then checked "Suppress ICE validation".
