A number of people have reported that the Real Statistics software “disappears” from time to time. The following describes what to do when this happens.
First of all, the software doesn’t actually disappear. What disappears is access to the data analysis tools via the Add-Ins ribbon. In fact the Add-Ins ribbon disappears. You can still access all the Real Statistics functions and you can access all the data analysis tools by pressing Ctrl-m.
The disappearance of the Add-Ins ribbon seems to be an Excel 2013 problem, and a weird problem at that, which is related to the sequence that Excel uses in activating add-ins. I will try to address the issue of the disappearance of the Add-Ins ribbon in the next release of the software, but for now if this happens, I suggest that you do the following:
(1) Press Alt-TI and unclick the add-in and click on the OK button.
(2) Close Excel and reopen Excel (I am not sure whether this step is necessary).
(3) Press Alt-TI, click on the Analysis ToolPak add-in and click on the OK button.
The key issue is that for some strange reason, the Analysis ToolPak add-in must be activated last (after the activation of the Real Statistics software or any other add-in).
Please let me know if you are still having problems with the Add-Ins ribbon access after applying this approach.
