BPC 7.5 upgrade issue

Hi Experts ,

We have upgraded 7.0 to 7.5 sp04,but we ar having issue with installaing the client and logging in to BPC for Excel. When we install the BPC for Office client or the admin console

Error Message : "You do not have authority to install the Planning and

Consolidation client"

Then click NEXT and continue instalaltion

It appears everything installs,but when we try to log in to the Admin console or Ofice Client message occurs

"The

system cannot connect to the (http://bpctest.int.XXXX.com) application

server"

Please suggest
