Hi. I am using MyEclipse 5.1 on WindowsXP (installed via the full stack installer). JDK1.5.
When I set my Windows Regional Options to “Thai” (which is what I use normally), and enter the key, MyEclipse said the key is expired. I have to change to English (United States) before it accepts the key as valid.
(I remember last year I had to do this also, but forget to report).
