I have nearly same problem as this question. If I want to import Excel tables with FlexSim 2016 I get the same error "OLE Automation Error" with "Failed to initialize Excel::_Application!". Up to FlexSim 7.7.4 we haven't any problems. I tried it on two computers, both with FlexSim 2016 16.1.2, Office 2007 and Windows 7 64bit with the same result. With 7.7.4 it still works fine on both computers. Any help is highly appreciated ;)
