On January 20th and 21st, due to some planned IT maintenance activities, some of the ESO services (P2PP, p2, Archive access, etc.) could suffer from temporary disruptions. We apologize in advance for the inconvenience.
The P2PP Tool - Download area
NB: Version 3.4.3 of P2PP fixed a bug related to the start of P100. Note that this version P2PP requires Java 1.7 or 1.8. Version 2.13.4 (for La Silla) also has some internal fixes for compatibility with Period 100 and requires Java 1.6, 1.7 or 1.8.
Please also make sure that you have Java 1.7 (or 1.8) installed on your machine. In case you do not, the links below may be useful:
