Yes, for the new Excel on PC version (Excel 2007 and Excel 2010 and later), you will need to precede the "S" with an "X" to access the Add-ins ribbon.
Thus, ALT+X+S and then the rest.

I have tried "Alt+X+S" and doesn't work. I can see that the add-in is installed when I go through the "Excel Options" menu, but do not see the add-in when typing in "Alt+X+S". All other functionality works. I have also tried to uninstall/ install a few times and stil... I have tried "Alt+X+S" and doesn't work.

Just to check - you are hitting ALT+X and then the letter S after the Add-ins ribbon appears. If so, when you hit ALT+X, does the "WST" sub-menu show up within the Add-ins menu? If WST doesn't show up, then the macros were not correctly installed. If WST does show up, are there any other ... Just to check - you are hitting ALT+X and then the letter S after the Add-ins ribbon appears.

If so, when you hit ALT+X, does the "WST" sub-menu show up within the Add-ins menu?
If WST doesn't show up, then the macros were not correctly installed.
If WST does show up, are there any other macros in the Add-ins menu?

When you hit ALT+X and you see WST, make note of what letter is highlighted. Sometimes if you have additional macros installed that have also assigned "S" as the "accelerator" key, then it might be S1 or S2, etc.

Let us know if you still have problems and we can troubleshoot further.

Yes you are right. It was not installed properly. After downloading the .xla, I opened Excel 2013 and then straight on to "Options", "Add-Ins", etc. However, what I did not do after downloading was to make Excel "recognize" the .xla file. I double clicked on the .xl... Yes you are right. It was not installed properly.

I double clicked on the .xla file, authorized the pop-up to open with Excel, and lastly, "Enable Macros".

Unfortunately, that is still not the correct way to install the macros.

please go here:

and click on the second link for video instructions.

I guess the problem is coming due to format issues. Make the file .xlsx and enable macro in the file menu. Then you can download the WSTMacros3.4.2 (full version) from the site referred above. It should work automatically then.
