How to restore a database from large sql file?

I have a 2 GB SQL file, generated from SQL Server database 2008, which includes data and schema. SQL Server 2008 Express does not even open the file saying an error:

Error: HRESULT E_FAIL has been returned from a call to a COM component

but, the file opens 开发者_Go百科in word pad while it just hangs after loading the file.

Any idea or suggestions what is the problem and how to overcome?

I experienced similar issue before, this is how I fixed it:

1. Go to Control Panel -> Clock, Language, and Region -> Change location
2. Change your location in the format tab to English (United States) and in the location tab change to United States.

Also please make sure that the Language for non-Unicode program section that you can find inside the Administrative Tab in the Change Location section should be set to English (United States).
