OfficeXP retail transformed into Enterprise?

[3dew]

Hi, I have the file: PRORET.MSI on my OfficeXP Pro disc, so this means no SP1 slipstreaming or unattended install is possible...

(from the guide):

Please note that you can only do a slipstream if you have PRO.msi or PROPLUS.msi, you cannot slipstream if your Office XP disc contains PRORET.msi.

Also there cannot be made an Administrative Installation Point with the Retail version...

Is there a way to change the PRORET.MSI file and/or another file so it IS possible to slipstream SP1 into it and make an Administrative Installation Point for unattended install?

No

No

Unfortunately that's right. I've got MS Project Professionall, for example, and can't do an administrative installation either. I'd need the Enterprise version.

So, if you don't have got the rigth version, there's no way except you spend money for a newer version.
