This error occure due to permission and require administrator rights while there are normal installation have some permission restrictions and inorder to overcome that issue you need to install management studio with administrator permission.
To do this do follwing steps:
For Windows 7 64 bit you have to use the 64 bit CMD prompt (I didn't even know there was a separate version) and then run this as administrator. So I did the following…
1. Right click on desktop and click NEW – SHORTCUT
2. Create shortcut to C:\Windows\SysWOW64\cmd.exe
3. Right click on the new shortcut and Run AS ADMINISTRATOR
4. Enter full path and file name:
e.g. C:\Pathtoyousetupfolder\SQLServer2005_SSMSEE_x64.msi
