[Lazarus] How to switch a project from 32 to 64 bit (on Windows 7 x64)?

[Patrick Chevalley]

I don't know your workflow and why you keep the old version of Lazarus? for maintenance of older version of your applications?

In this case do not remove them but install the 2.0.2 Lazarus and cross-compiler in a new Lazarus 2.0.2 directory then create a new config for 2.0.2 as usual.
