If you are not comfortable using the self reg table in Wise for registering DLLs, here's a WiseScript that can register the set of DLLs in the application. Better yet, the WiseScript can be used in a custom action. Please find attached the script that accepts the location of the DLLs from a text file. Update the location of DLL in the text file, compile the WiseScript, and use it in custom action. Cheers !!
If it is required register dll files it can be done with Vbscript with following line of codes. Set oShell = CreateObject("WScript.Shell") oShell.Run("regsvr32.exe /s " & "<Path of dll file>")
