In this final part of the series, we will take a look into the basic requirements to develop Symbian applications.
| Item | Requirement | Comment |
| Host OS | Windows XP SP2 | Later service packs than SP2 will generally work, but are “not supported” |
| Host OS | MS Vista | See compatibility information. |
| CPU Speed | 1.8 GHz | |
| PC Memory | 2GB RAM | Recommended for smooth operation of the IDE and Kits. |
| HDD | 4 Gb + | The Tool kits (PDT/ADT) occupy approximately 1Gb of hard drive space. Application developers require a further 2Gb per ADK with additional space for the actual builds.
Product developers require up to 100Gb for a full product build. |
