4. Important: 64-bit Environments and iGrid
-------------------------------------------
iGrid ActiveX exists only in the form of a 32-bit OCX control as the development environment it was developed in, Visual Basic 6, does not allow to produce 64-bit executable code. Unfortunately, Microsoft broke the backward compatibility for 32-bit OCX's with the release of the 64-bit Office 2010 (
http://msdn.microsoft.com/en-us/library/ee691831.aspx), and iGrid ActiveX cannot be used in the 64-bit editions of Microsoft Office 2010/2013 because of that.
However, it works well in 32-bit editions of Microsoft Office, even in 64-bit versions of Microsoft Windows. We highly recommend that you use 32-bit editions of Microsoft Office for your real-world developments because of similar compatibility problems with many other components in 64-bit editions of Microsoft Office. There are many good resources regarding this issue in the Internet, and one of them is

There is also just one demo installation of the product which installs the 32-bit iGrid OCX, its demo as a 32-bit exe and a set of VBA samples. The exe demo can be launched without any problems in 64-bit versions of Windows. If you open the VBA samples and do not see the iGrid OCX controls in forms or get error messages that the control is missing or not registered correctly, first of all check the edition of your Microsoft Office (32/64-bit). If it is a 64-bit one, open the iGrid VBA samples in a 32-bit edition of Microsoft Office.
