We're attempting to install MassHunter Workstation Quantitative Analysis Reporting B.07.00 but it keeps failing with an Error: Unable to get the Add property of the AddIns class about halfway through the process. All other software and reporting has installed and is working. If you acknowledge the error the process continues and appears to install but you are unable to generate reports. OS is Windows 7 Professional with Service Pack 1 (64-bit) and Excel 2016 on an HP Z230 with 8GB of memory. Any ideas would be greatly appreciated.
