Hello Seyyid,
Thank you for your question. In order to use the excel plugin there are a few prerequisites that need to be met.
Prerequisites:
- Windows Vista/7/8
- Runs on 32 and 64-bit systems
- Microsoft Office 2007, 2010, 2013
- Microsoft .NET Framework 4 (download)
- Microsoft Visual Studio 2010 Tools for Office Runtime (download)
If you have a previous version installed you will need to remove that version first before installing the new version.
For you reference I have included the help link that explains how the excel plugin fuctions.
