Tip: It's perhaps a good idea to reboot your Windows system after you have installed Lazarus and before you try to install additional Lazarus components such as zeoslib for example. You will be taken through a typical Windows installation wizard to install the FPC compiler and FPC source within the same directory structure as Lazarus IDE, and Lazarus should launch and operate without significant problems, provided you have uninstalled any previous version of Lazarus and/or FPC which was not installed with a recent version fo the Windows installer (older installations can often be found in the C:\pp directory).
Upgrading can be as simple as downloading the new installer and running it. See section Preparation for the first start below. For this purpose Lazarus offers to write its configuration files into a specific directory so that both versions can coexist. If you already have another Lazarus version on your system it is recommended to keep the old version and to keep it separate from the new installation. Moreover, it is recommended to avoid spaces in the folder name because it may confuse some tools used by Lazarus. The current releases of the Windows Lazarus installer packages install very easily, and should work 'out-of-the-box'.ĭo not install into the standard program folder c:\Program Files because access to it is restricted.
