Installing the OfficeWriter Designer 8.1.0 and higher throws the error:
No Office 2007 or 2010 found. Office 2007 or later must be installed to use this product. If you are using an earlier version of Office please download the installer version 8.0 or earlier.
Office 2010 is installed
This error may occur if you have the 64-bit version of Office 2010 installed.
The OfficeWriter Designer does not currently support the 64-bit version of Office 2010. There are no immediate plans to support the 64-bit version of Office 2010 because we have not seen much demand from customers and Microsoft recommends using the 32-bit version in most cases:
IMPORTANT The 32-bit version of Office 2010 is the recommended option for most people because it prevents potential compatibility issues with other 32-bit applications, specifically third-party add-ins that are available only for 32-bit operating systems. — Choose the 32-bit or 64-bit version of Microsoft Office.
The OfficeWriter Designer is supported on 64-bit operating systems, but requires a 32-bit version of Office. If no 32-bit version of Office 2007 or 2010 is detected on the machine, the installer will throw the error above.
Office 2003 is installed
Starting in OfficeWriter 8.1, the OfficeWriter Designer is only supported in Office 2007 and 2010. If you need to use the Designer in an earlier version of Office, please download OfficeWriter Designer 8.0 or earlier.
No Office is installed
The OfficeWriter Designer is an Office add-in and requires a 32-bit version of Office to be installed.
