Excel reading in asp.net

Hello Experts!

I have attached the code but I am finding the following issue when I host this on the IIS 7 on the Windows Server Standard FE Service Pack 2

The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.

The problem is coming because of the following:
connectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + fileLocation + ";Extended Properties=\"Excel 8.0;HDR=Yes;IMEX=2\"";

I did enable 32 bit true of the application pool assigned but then it gets to the  following problem:

The requested page cannot be accessed because the related configuration data for the page is invalid.

Thanks

What exact OS version are you using?
You may need to reinstall Microsoft.Jet.OLEDB.4.0 driver,  check:
http://stackoverflow.com/questions/1991643/microsoft-jet-oledb-4-0-provider-is-not-registered-on-the-local-machine

Also you need to recompile your site as 32 bit (x86) application.

I tried to install http://www.microsoft.com/en-us/download/details.aspx?id=13255

but it says  I need to uninstall 32 drivers first from the Server, I don't know how to uninstall that that.

What it means is that driver is actually installed, thus no need to install anything.
If that is the case you should recompile your site as 32 bit (x86) application and configure IIS app pool site to run 32 bit apps:
- Open IIS
- Change the appPool on Advanced Settings to true to enable to 32-bit application.

If the above does not solve and you still has the requested page access error message, you may have permission issues or your web.config files is corrupted, check:

and if do enable 32 bit application as false then:

The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.

I tried installing 64 bit on the 64 machine i.e on the Server and I found the attached error.

I resolved the following error
The 'Microsoft.Jet.OLEDB.4.0' provider is not registered on the local machine.

by installing the AccessDatabaseEngine_x64.exe on http://www.microsoft.com/en-in/download/details.aspx?id=13255

but because the server is 64 bit so I have to uninstall the 32 bit based Office 2007 from the Server.

Moreover I used only Microsoft.ACE.OLEDB.12.0 (for 64 bit)  instead of Jet.OleDB.4.0 (32 bit)

Yes we can force Jet OleDB to run on 64 bit by enabling 32 bit true forcefully but it was  not required as I used ACE.OLEDB.12.0
