Thank you for reporting this Antoine - this answered my problem and I got the installer build fixed!
I solved this the second way, went to the lvproj file. It may be helpful to know that the lines you must be looking for will contain some of these strings:
<Property Name="RegDest[0]
<Property Name="RegDestCount"
<Property Name="RegGroup[0]
<Property Name="RegGroupCount"
-- by deleting all the properties starting with these tags I was able to get a working installer build.
You want to take a backup of the project file first of course
