EXCHANGE 2013 - setup.exe schema prep error

Question

Trying to install exchange 2013 sp1 (downloaded from here:
http://www.microsoft.com/en-us/download/details.aspx?id=41994).
on 2012 r2 server.
After I run (with domain admins affcourse): Setup.exe /prepareschema /IAcceptExchangeserverlicenseterms
I recieve an error that user is not a member of schema admins and enterprise admins but I have double checked that account is in those groups. So, what am I missing there?

Hi Joe,
since we can make sure the user account is a member of Domain Admins, Schema Admins and Enterprise Admins groups, please also add the user to be a member of Organization Management group, don’t
just add the Domain admin to the Organization Management group, please directly add the account to the member of Organization Management group.
Then check if the account inherit permission form its parent level. To do this, please refer to the following steps:
Open ADUC, select “View->Advanced Features”;
Navigate to the user account you used, check its
Properties;
On the
Security tab, click Advanced, please make sure the inherited permission is enabled in the lower left corner. If not, please click “Enable Inheritance” to enable it.
Then use this account to login the server;
Right click “Command Prompt” and choose “Run as administrator”, then navigate to the setup file location, try to prepare schema by command:
Setup.exe /prepareschema /IAcceptExchangeserverlicenseterms
6.  If issue persists, please try Mavis’s suggestion to create a new user account, use above steps add the sufficient permission, then check the issue again.
Meanwhile, what do you mean by “single label domain”? Do we have a single domain and prepared DC/GC, or have parent/child domain configuration.
