How do I get a VC8 DLL to work with a VC7 application?

How do I get a VC8 DLL to work with a VC7 application

'App.exe': Loaded 'T:\Debug\Module1.dll', Symbols loaded.

'App.exe': Loaded 'T:\Debug\Module2.dll', No symbols loaded.

LDR: LdrpWalkImportDescriptor() failed to probe t:\Debug\Modlue2.dll for its manifest, ntstatus 0xc0150002

Debugger:: An unhandled non-continuable exception was thrown during process load

I read about embedding manifests, toying with the /ALLOWISOLATION:NO, etc. Can someone tell me if and how it can be done

Thanks
