BPC 75M - Modify Application error "Cannot connect to the Reporting Server"

Question

I have trouble with Modify Application, also in ApShell. Maybe you have a clue what it can be the problem.
Configuration: single server BPC 7.5M SP3, Windows Server 2008 SP2, SQL Server 2008 SP2
Installation user is a domain user.
No errors during installation, no error in Server Manager diagnostics.
But when I try to modify an Application from BPC Admin it gives an error for step "Make OLAP database and Journal/Audit reports. / Validate dimension formulas.".
In tblLogs I see the error message:
==============[System Error Tracing]============== [System Name] :
AdminServerHandler [Message Type] : ErrorMessage [Job Name] :

Answer 1

There were problems accessing the web page   HTTP://server/reports
Error message:   "Reporting services 2008 user does not have required permissions"
It was possible to open the page  HTTP://server/reports with local administrator user and  I fixed this problem by performin following:
- add Content Manager right to bpc installation user
- disable UAC from Windows Control Panel  > User Accounts
Still Modify Application gives the same "Cannot connect to Reporting Services".
I tried:
- check that BPC Installation User is part of Local Administrators
- reboot server
- reinstall BPC after disabling UAC
- reinstall everything except the Windows Server 2008
- I installed another computer with the same exact configuration but with a local BPC Installation User and it works.
Have anyone installed BPC 7.5M SP3 on single Windows Server 2008 SP2 , with SQL Server 2008 SP2 and with BPC Installation user a domain user?
Maybe you have an idea of what I should check next.
Thank you,
