office 12 installation corrupts office 2003

[sphinx]

HI,

want to have a look at new office 12. I chose to kept the old version
and only installed outlook 12 and powerpoint 12. After installation, I
get "mapi was unable to load the information service mspst.dll" for
launching both outlook 12 and outlook 2003. After " detect and repair
errors in my office installation" in 2003, the same error remains.

Really don't want to reinstall since there are a lot of customization
and plugins involved.... anybody can help?

Thanks!

Your question should be directed to the private newsgroup listed in your
beta testing instructions.
You ought to know by now that you can never install 2 versions of Outlook on
the same partition.
