The following line
<Component Guid='{THE_GUID}' Id='GlobalScopePackages' >
Generates the following error:
Error 4 ICE80: This 64BitComponent GlobalScopePackages uses 32BitDirectory blablabla c:\development\...\file.wxs
Error is described on this page http://msdn.microsoft.com/en-us/library/aa369034(VS.85).aspx
How do I fix this or suppress the warning? Is it safe to simply supress the warning?
You can also set Win64="no" in the <Component /> tag of the components which are not 64-bit.
But I can confirm you can ignore this.
I wanted to be able to build my installer both for x86 and x64 depending on the build arguments passed in. I was able to do it like this.
See this blog post by Alek Davis for more information.
Simple example, in the .wxs file
<?if $(var.Platform) = x64 ?>
<?define Win64 = "yes" ?>
<?define PlatformProgramFilesFolder = "ProgramFiles64Folder" ?>
<?else ?>
<?define Win64 = "no" ?>
<?define PlatformProgramFilesFolder = "ProgramFilesFolder" ?>
<?endif ?>
