Consistency would be nice, I agree, which is one reason for not modifying the SoftQuad registry key despite the fact that we are now three companies beyond that. Part of the inconsistencies that you are seeing between versions is very possibly to do with the fact that we have used different versions of InstallShield over the years to create our installers (as we have been forced to upgrade that software) and it is constantly changing as well.
What you have figured out is the only way I can think of to get the information you are looking for.
There should be no way to have more than one version installed unless perhaps you have 1.x, 2.x or 3.x. Our 4.x and up installers are supposed to detect other versions of the software and ask you to remove them before they will install. If you do manage to have more than one version of XMetaL Author installed at once (including 3.x and earlier) that [u]will[/u] cause problems and should be avoided.
