Eclipse no se inicia en Windows 7

Nuestra compañía se está mudando a Windows 7. Después de recibir la actualización, Eclipse ya no se iniciará en la máquina de anyones. Primero probé con 3.4 y también probé lo último y lo mejor. También tengo instalado el último JDK, que es 6 actualización 18. Esta es una máquina de 32 bits. ¿Algunas ideas? Aquí está el archivo de registro que Eclipse está generando:
