Error using Excel 2010 PowerPivot addins to connect to Oracle database

Hi,

I was using MS Excel 2010 with the PowerPivot add-on to connect to Oracle database when I got this error message, see below.  I checked Oracle and it seemed working fine.  I searched the internet and found a workaround which I followed but couldn’t get it done right. 

Can someone help me here, instead?   Please help.

PowerPivot for Excel

Failed to connect to the server. Reason: ORA-06413: Connection not open.

Hi there SheilR,
 
The problem you're facing used to be a very well known bug in one of the previous Oracle editions happening when users are using 32-bit Excel on 64-bit machines.
 
The quickest way to solve your problem is to update your software and your OS and to keep them all up to date or to use 64-bit compatible version of the software.
 
There is also a simple workaround that will solve your problem – you just have to access the Excel using the shorten path instead of the full one. Full tutorial can be found on the following link.
