InstallShield.msi.interop backwards compatible?

Hi,

I have a ManagedCustomAction dll that I created, that is referring to InstallShield.msi.interop from IS 2010.
I have been using it for a year, in an installation.
We have upgraded the version to IS2011.
I am wondering if I should rebuild my ManagedCustomAction dll, with a reference to InstallShield.msi.interop from IS 2011, or if InstallShield.msi.interop is backwards compatible. (in the IsClrWrap table of the installer, the link points to the IS2011 version of the interop dll, but the custom action dll was built with the IS2010 version).

Thanks for any help,

Claire

While we haven't tested for backwards compatibility, I do not believe this DLL has changed materially either. I don't think you should have problems going with either version of the file, aside from possibly needing to recompile.
