How do I upgrade PersisTables from 32 bit Excel to 64 bit Excel?

In order to upgrade to 64 bit Excel it is necessary to uninstall the 32 bit version of PersisTables. This can be done by rerunning the original install package and choosing the Uninstall option or going to the ‘Programs and Features’ page of the Control Panel and uninstalling the 32 bit version of PersisTables.

To uninstall from the Control Panel->Programs and Features window, right click on the PersisTables tools and select Uninstall option.

The Excel Registration Tool should be removed prior to removing the PersisTables Toolkit for Excel.

Once removed and the 64-bit version of Excel has been installed, the 64-bit toolkit can be installed using the 64 bit install package.
