It sounds like creating a clone at this point is a bad idea if I were
to go backwards to fix it because I would be in the same mess as
the guy in the link you gave but how do we resolve the problem ?

I did a search on Agent Ransack(basic) for Profiles.ini and it also
found Sea Monkey

How do I proceed?

Here is how you back up the Seamonkey folders for later.
Two data folders to back up.

You could back up Profiles.ini file as well, but
there isn't much reason for it to change.

In total, there are a bunch of things, but you don't
need all of them.

Program Files === This is handled by the SM Installer

profiles.ini === Has the identifier of which folder is important.
Double click to open in Notepad.
Profiles === Folder next to profiles.ini
Contains multiple profiles sometimes but not always.
These guys are in the Roaming section.

Roaming === SQlite databases. \___ The named folder
Local === Cache folder. Cache2 is mostly junk. / in each.

Here is a sample picture of a Windows 7 Seamonkey setup.
I have put the named folders, into separate folders for
later, to keep which is which straight.

Double-clicking Helper.exe should cause Seamonkey to uninstall.
I expect it is reading the log file next to Helper.exe,
to figure out what to delete. It will not delete the
two "named" folders.

When you go from 2.53.5 to 2.53.7, there is nothing to do
to the "named" folders (you made your *backup* before
installing 2.53.7).

Seamonkey will adjust the folder contents for the
new (2.53.7) version of software.

However, if you install 2.53.5 again in place of
2.53.7, now the "named" folders need to be rolled back.
You delete the "local" one and the "roaming" one, then
go to your backup stick, and copy the "local" to the "local",
the "roaming" to the "roaming". Then, when you install
the 2.53.5 older one, the version of Seamonkey matches
the two "named" folders. No file modification is necessary
by Seamonkey, because it notices the versions match.

As long as you don't lose the named materials, you should
be able to figure out, with Agent Ransack searches, where these
items are. Only too much "deleting", would remove all traces
of what the profile name should be. And the backed-up
folders have the name in them too.
