hi I've installed a software with a key for amateur version. Now i've got the key for a professional version. How do i update the registry key. When i reinstall the software it picks the first key by default.
Thanks in advance.
regards,
arul.

Have you uninstalled the amateur version? Perhaps the best people to ask will in fact be the software provider. What is the software called?

yeah i'v uninstalled & tried installing it again. it picks the key by default

... and the software is? I'm assuming it's not a cracked copy?
