I use an Imac that my wife and I share. Can she install lightroom on her user without us having to buy another user licence? Hope someone can help...
The license owner may install and activate on 2 computers, as long as only one is being used at a time
Cloud License allows 2 activations http://www.adobe.com/legal/licenses-terms.html
-Install on a 2nd computer http://forums.adobe.com/thread/1452292?tstart=0
-Windows or Mac does not matter... 2 on the same operating system, or 1 on each
-Two activations on one account MAY NOT be in use at the same time (note in the above license link)
