Can two occurrences of Lightroom run at the same time on the same computer?

[mpost]

I am looking to see if you can run two occurrences run on the same time on the same computer?  I am looking to add keywords to my wife's Lightroom photos that we have taken on various trips.  I have all the GPS info and have added keywords to best describe our trips to my images, but now would like to add that to her photos. Both our MacBook Pros are the same running the same software.
Or is there a better way to achieve this?

thanks

No. You can only have one catalog open.

There is a way to export as catalog from your computer but must include one photo. You could then Import that to wife computer and the the key words and metadata will carry over. Then just delete the one photo.

There are video tutorials, Multi-catalog Workflows, by Peter Kroug at <damuseful.com> for step by step instructions.

Thank you.
I guess I was partially there as I always export my keywords then import into my wifes computer.  Then I put the two computers side by side and just add the keywords manually.  Long but gets the job done. This may shorten my time.
I will try your suggestion.
Again thank you.
