Ow, a language thing is it ?

The master collection is for UK, I'm on NL..

"

The following language-specific software installs two language packs. Each line represents a new language group. You can serialize from either language in the pack. You don't get an invalid serial number error if you install in one language and serialize in the next.

• en_US (Universal English)\en_GB (International English)
• fr_FR (French)\fr_CA (French Canadian)
• es_ES (Spanish)\es_MX (Latin American Spanish)"

How do I "serialize from either language in the pack" ??
