Hello Sreebha,

It may be. If your installation delivers and registers AddinExpress.IE.TLB, this may result in the need to reinstall Add-in Express. Always exclude all .TLB and .OLB files unless you know why you deploy them.

Re installed add-on.We are trying to register through Visual studio by right clicking the project-> Add on express->Register.

Getting error as

The assembly "C:\Projects\SreeTest\SreeTest\bin\Debug\SreeTest.dll" could not be converted to a type library. Type library exporter encountered an error while processing 'SreeTest.IEModule, SreeTest'. Error: Error loading type library/DLL.

Could not find .tlb files.

Please advise.

Have you reinstalled Add-in Express? Does your setup project refers to a .TLB file? If so, uninstall your add-on, exclude the .TLB file from your setup project and then reinstall Add-in Express.

If this doesn't help, create a new ClassLibrary project in Visual Studio and check the 'Register for COM interop' option in the project properties (see the 'Build' tab). Then rebuild the project. Do you get any errors/warnings in the 'Error List' window?
