I've downloaded ExcelUtilities.exe (from www.appspro.com) and saved it
to my C:\PROGRAM FILES folder.

Then, I double-clicked on "Excel Utilities" and it installed
successfully.

I then started Excel and opened an Excel workbook.

However, when I clicked on Tools/Add-Ins, put a check in the "Excel
Utilities 2.0 box and clicked OK, an "Excel Utilities" box is being
displayed which says: "Invalid procedure call or argument
(ctlAddNewControl())"

How do I resolve this problem?
