Windows installation over an exiating version

[Jean-Pierre Chrétien]

Dear developers,

A recent exchange on the lyx-fr list pointed out the fact that
  * installing 2.3.5 without removing 2.3.4 creates all right a 2.3.5 registry 
entry;
  * however the 2.3.4 registry entry is still there, but does not point on anything;
  * desinstalling 2.3.4 removes 2.3.5.
The only way out is to kill directly the 2.3.4 registry entry.

Can this be reproduced (I'm on Linux)?
