Consider the following scenario:
  • You have Microsoft Office Click-to-Run 2010 installed on the computer.
  • You try to install Microsoft PowerPivot for Excel.
In this scenario, PowerPivot for Excel does not install. Additionally, you receive the following error message:
PowerPivot for Excel Setup

Setup is missing prerequisites:
This add-in requires Excel 2010. If you have 32-bit Excel, you must install the
32-bit version of the add-in. If not, you must install the 64-bit version.

This issue occurs because Office Click-to-Run 2010 is installed within the virtual application space that is created by the Microsoft Click-to-Run technology. Therefore, the Setup program for PowerPivot for Excel cannot locate an installation of Microsoft Excel 2010.


To resolve this issue, you have to install the .msi-based installation of Microsoft Office 2010 or of Microsoft Excel 2010.

To do this, uninstall Microsoft Office Click-to-Run 2010. Then, install Microsoft Office 2010 or Microsoft Excel 2010 from an installation DVD or from another installation point.

To determine whether you are running a Microsoft Office Click-to-Run 2010 installation, click the File tab, and then click Help. If there is a Click-to-Run Product Updates section, then you are running a Click-to-Run installation.

To uninstall the Microsoft Office Click-to-Run 2010 installation, follow these steps:
  1. Click Start, and then click Control Panel.
  2. Click the Add or Remove Programs item or the Programs and Features item.
  3. In the list of installed programs, click Microsoft Office Click-to-Run 2010, and then click Uninstall.
  4. Click Yes when you are prompted to remove all applications that were installed by Office Click-to-Run. For example, you may be prompted to remove Microsoft Office Home and Business 2010 or Microsoft Office Home and Student 2010.
