My application is install in Windows Server 2008 R2 64 bit machine. But MS Office-7 32 bit install in that server. MS Excel application permission has been given to Every User from DCOM Config. This Configuration was fine to create an excel from my asp.net web application.

But to upload Excel data through my application was not work on that time due to 64 bit machine and MS Office 32 bit configuration. To solve this problem, I Install "AccessDatabaseEngine_x64" software in Server and give MS Excel Application permission to "Every One" from DCOM Config.

Now my upload excel problem has been gone. But create an excel from my asp.net web application not work.

Please help me. thank you.
