VB Setup Wiz and Registering Files

My VB5 app, created by Setup Wiz, has to register a file (ttsmgr60.dll) in Windows\Lhsp (a new folder) on the destination pc. If I include the line $(DLLSelfRegister) in the Files section of the VB SetUp Wiz setup.lst file, it all installs OK, but then, on run, says it can't find the file. The file is supposed to be self-registering. It does not appear in the registry. How do I register a file on the destination pc. Do I have to edit setup1.frm with CreateRegKey etc.
