I used to have Eclipse 3.5.2 working from my Limited User Account (i.e. not Administrator).
But when I upgraded to 3.6.2, Eclipse refuses to run in the Limited User
Who has write access to the directory: C:\eclipse & C:\eclipse\configuration ?
AFAIK eclipse decides, on startup, whether to use the central installation as the configuration location, or a user accessible directory based on whether the eclipse (or possibly the configuration) directory are writable.
