Create Pure 64bit setup that includes InstallScript CA ?
Hi
I'm using Basic MSI project with InstallScript CA.
Is it possible to create a pure 64bit setup ?
When I build the setup I get this error
error: ISDEV : error -7318: InstallScript Custom Action TEST must not be included in a strict 64-bit package.
WOW64 support is optional on Windows Server 2008 R2 and newer, so there could be situations that these custom actions will not be able to run. However, since the majority of setup.exe based installers, including Microsoft's installers, are 32-bit, disabling the WOW64 feature runs the risk of not being able to install a number of software packages.
This error can be ignored unless you absolutely need to ensure that your setup does not contain any 32-bit install time code. If this is a requirement, a 64-bit MSI DLL action should be used instead of InstallScript custom actions.
