Question: i1Share does not see the Eye-One Pro on my Windows 64 bit system. How can I solve this?

Answer: i1Share 1.4 will not work with 64-bit systems because the included EyeOne.dll file has not been updated for 64-bit support. This is why the Eye-One device will not be recognized on Windows 64-bit systems (XP, Vista, 7). To work around this issue, close i1Share, disconnect your Eye-One, then download and install Eye-One Match 3.6.2 or i1Diagnostic 2.5.1. Now navigate to the Eye-One Match (C:\Program Files (x86)\GretagMacbeth\i1\Eye-One Match 3) or i1Diagnostics (C:\Program Files (x86)\X-Rite\i1Diagnostics) program folder, copy the EyeOne.dll and replace it in the i1Share program folder (C:\Program Files (x86)\GretagMacbeth\i1\i1Share). Plug in the Eye-One and launch i1Share software. The Eye-One should now be recognized. 

While this should work, this is an UNSUPPORTED work around.  If this fails to provide connectivity to i1Share, the user may want to consider looking into a third party application for spot measuring capabilities.
