I am trying to install SQL Server 2008 R2 in my machine. The following error occurs during the installation:
"is not a valid login or you do not have permission.
In Server configuration, I used the "Use the same account for all options" and it was NT AUTHORITY\NETWORK SYSTEM. In the authentication mode, I selected the "Mixed-mode authentication" option and provided the password "open"
for the account "sa". I am installing the SQL Server 2008 R2 in E: drive, while the shared location is in C: drive. I am running the installer in administration mode.
The machine is a 64-bit Windows 7 Ultimate with 1.00 GB RAM, Pentium Dual-Core Processor 2.5 GHz.
