I had 2 cases in a week of customers complaining about getting Error when they open BI Administration Tool. The same error: [NQSError 46036] Internal Assertion: Condition m_pFile->Read(bytes,sizeof(data))==sizeof(data),file server\objectmodel\Src\SORpArchivePersistStream.cpp,line 373.
The solution is to upgrade/reinstall the client from the patch.
The 11.1.1.7 case: In patch of 11.1.1.7.131017 there is a zip file of p17463403_111170_Generic. In side it,under 17463403\files\clients\biserver\ you will find 2 client installations: biee_client_install_x64.exe and biee_client_install.exe

Use the relevant one to upgrade the clients. If you installed OBIEE on Windows server,the Administration on the server is upgraded automatically.
