Change Office Enterprise to Office Professional

Hi,

We are busy getting our licenses in order - taken over from previous engineer.

We are noticing that the Office packages installed is Enterprise 2007 and we have Professional 2007 keys.
Is there any way that we can change the version of the installation without a un/re install? (via registry or something)

We have tried to remove the keys from the registry and re-activating the install but no luck.

Registry changes will not work in this kind of situation.
I think you should uninstall the Enterprise 2007 and then install Professional 2007.

Is there any particular reason you want to downgrade? you could use a tool like Belarc or Magical Jellybean Keyfinder and Note down the keys for the Enterprise editions.

But from my understanding, you need to reinstall the correct version of Office 2007 to be able to downgrade

I think you should be able to follow the step in the link provided below. I've never had to use it myself but you can try it and see if it works

I'm not even sure how legal that is but if you are trying to get legal I guess MS will not have issue with it. Otherwise maybe reinstall is your only reliable route.

Maybe I wasn't clear enough.

We have Professional licenses, not Enterprise licenses - the previous engineer was a pirate so he installed some Enterprise version.
I have already tried changing the reg keys as by the method given above - it did not work.

We need to change the VERSION of the Office suite from Enterprise 2007 to Professional 2007 and only then change the keys.

I want an easy way to do this through the registry or something, without the un/re install. -if possible.

I'd agree with Abaraj - to ensure you are completely legal i'd also recommend a full removal and re-installation.

If you create a slipstream copy of office with your key, you can easily roll it out to as many people as you require....... -
