I have a com dll. With my major release this DLL is not registered.

WIth patch i want to register this dll. When i compile IS package for the patch information about this Dll is added in class table. Information is added when i use " Com Extract at build " OR extract registry data.

While patching Major release MSI and patch MSI are compared. Since information about COM dll was not present in Original MSI i get validation warning Val 0015. " Class table contains new information. Patch become uninstallable"

If i remove the information from Class table patch can be installed but com registration fails.

Is there any fix for this issue ?

Actually, Val0015 warns that the patch will not be uninstallable, i.e. users will not be able to uninstall the patch to revert the product back to the un-patched state. This shouldn't be a problem.

We do release patches after every 2 to 3 months. Many times its required that user needs to uninstall the patch and revert back to original product.

So i need patch to be uninstallable in any case.

Is there any way by which i can hide changes in Class table from patching mechanism.

One of the solution can be merge registry file. But this does not work for COM component.

I tried creating another component with different name but still same validation problem.

Maybe you should keep your COM data stable between releases.
