ExceLinx is obsolete and unsupported software.
Due to changes in Microsoft Office architecture, macros such as our ExceLinx software became unusable after Office 2010.
Unfortunately, Keithley has no ability to assist with this software and can only recommend that you develop a new program for instrument control or use our current control software, KickStart:
