IPhoto failure after updating to Mavericks

Question

Helping out my neighbor.
On 2 April, she logged into the App store and, using her Apple ID, she downloaded and installed Mavericks.  Her 7 year old iMac is currently running OS X 10.9.2.
I tried to launch iPhoto and got the alert <You can’t use this version of the application ‘iPhoto’ with this version of OS X.’
When I went to App Store > Updates > iPhoto,  the App store screen opened with her Apple ID already filled in and the password blank. Filled in the password and were greeted with:  Update unavailable with this Apple ID.  This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or canceled.”
FWIW, since 2 April, she was offered and accepted the Security Update 2014-002.
Also, under Store in the menubar, there is : Sign out (so she is signed in) and View My Account, followed by her correct Apple ID name.
Found, under the App Store categories, a small screen shows: Welcome (her name), Account, Redeem, Support.
When I clicked on Account, we were asked for the password and then were taken to the Account and all the information was correct.
Can anyone suggest why she is being greeted with the - Update unavailable with this Apple ID.  This update is not available for this Apple ID either because it was bought by a different user or the item was refunded or canceled.”
I believe she has to buy a new copy, but how do we get iPhoto at the App Store to change from Installed to Purchase?  Delete the non-functional copy of iPhoto from her iMac?
Thanks ever so much
