I took a look to the registry and it seems that also side-by-side 
installation is not fully supported: you can make a new install in a 
different directory, but you probably can't uninstall the previous 
version any more, since the registry is rewritten.

To fully support side-by-side installation we should introduce separated 
registry entries for different SDCC versions...

This is not so trivial as it looks: how can the new installation know 
where the previous installation has been installed? Actually it could 
with help of registry, but currently this is not implemented.
