hi ...yes, please more closely examine the steps: step 7 closes 2014, step 9 opens x64 -- as the steps indicate, only one version of ps was executed at a time..
on windows 7 x64
also have identified that in windows, OPEN WITH defaults to PS CC even though File_Associations show CC 2014 ... there's some redirect that is happening.
the Cloud update didn't have any errors.
