Nsis Vs Installshield Update
There's a comparison of features etc here: and 'better' is a bit vague - it might include cost, MSI features you can use, ease of use etc. It might be useful to say why you are looking elsewhere. I'll also add that I hope you aren't confusing the tool with the underlying MSI technology and the design of your installations. If you have setups that try to do a lot of complicated things during an install (typically custom actions, including installer classes) then the issues won't change just because you decide to generate your MSI with WiX instead of InstallShield.

This is extremely simple, and unlikely to trigger the NSIS error, but you can try it as it has been known to help. Locate the setup file, and Right-click it, and select Rename from the list.
