We register the capabilities of Delphi applications using TLB files. However, from reading MSDN documentation, \"Installation package authors are strongly advised against us
It means you would need to figure out what registry entries to add to register the tlb. This explains what needs to be done. You could also use a tool like REGCAP.EXE which comes with Visual and generates a .reg file. If you use WiX to build your msi you could use tools like tallow and heat to let them generate the wix files for you.
