Software Deployment

Hmmm...I wonder if it's telling you that a dependency is missing...?

As usual [yawn], your favoured file/registry/process monitr will tell you what's missing.

As we have a dependent dll for the SecureExcelDCF.dll & SecureExcelDCF.tlb files.so the dll and tlb need to place in the folder where the Extensibility.dll is present.So this will be a successful registration of the DLL.

gives the successfull result when you execute the regasm.
