Without any parameters the settings are saved in %APPDATA%, so any 
Lazarus would use/overwrite the settings of the other Lazarus. You MUST 
pass the pcp parameter to all installations if you want different 
configurations (Note: You can leave out the parameter for one 
installation which will then use the default location).
