Issue Details

Why do I get  Error 3001 like below figure 1 when I try to load a VI that contains an ActiveX container?
  

Figure 1. Error 3001

Solution

There are three different reasons why this error will occur which are listed below:
  • Some of the ActiveX components are not supported by 64-bit systems. LabVIEW cannot load a 32-bit ActiveX object into an ActiveX container in 64-bit LabVIEW because a 64-bit process cannot load a 32-bit process. To work around the problem, you can install LabView 32-bit on a 64-bit machine.
  • This error will also occur when using the Report Generation for Microsoft Office VIs to access Excel. When building your custom report in Excel, you can create several different worksheets and change their properties like their names. After manipulating these properties, the ActiveX calls to place data in Excel worksheets like Excel Easy Table VI will need a reference to the worksheet to place the data in. If this isn't provided, the ActiveX code will produce Error 3001. In order to fix this error, place the Excel Get Worksheet before calling VIs like Excel Easy Table VI or Excel Easy Text VI.
  • This error will occur if either the Excel Get ActiveX References.vi or Word Get ActiveX References.vi were used and then these ActiveX references were closed.  Other Report Generation for Microsoft Office VIs use these references and will throw this error if the references have been closed.
