Hi there

This is my first post so please be patient.

A user who has been using Power Pivot for generating various reports/data sets to see if it is viable for our company's needs and possible implementation going forward.

Whilst manipulating the data the user got the following error message:
Error1.png

Which when expanded gives this:
Error2.png

Background:
Windows 8 Enterprise (x64)
Microsoft Office 2013 Professional
After getting this error the user tried to narrow the possible causes but going through the data, reducing the size of the data and then removing all connections to databases and using data wholely contained within the data sheet.
So just to recap, there is NO LINKED DATABASE DATA involved.

I have done the following to resolve the issue:

1. Installed the latest version of Dot Net Framework 4.5.1
2. Installed all Office Updates
3. SQL Native Client 2008 R2
4. SQL Report Services
5. Uninstalled Office 2013 x86 and Installed Office 2013 x64 (that didn't solve the problem and I have since removed x64 version and put x86 version back on.
6. Installed Visual Studio 2010 Tools for Office Runtime


I have run out of ideas, please could you halp me resolve this issue?

Thanks
Andrew
