Remove/delete Excel Add-in - error message keeps popping up

This is on a machine I don't have access to at the moment, however, I can paraphrase. An error message appears when opening excel and is trying to open an Excel Add-in .xlam file, but I wish to remove that add-in because the location of the file is moving. I have attempted to remove the add-in when prompted, but when I come back to excel on that machine, it reappears with that same address.

I did this removal process once before, but stupidly did not document it and cannot recall how I corrected the issue. Please let me know if I must elaborate.

Edit: Here's the process I attempte

- Get out of Excel.
- Use the tools in Windows (such as the Search tool) to locate the add-in file you want removed. You can locate add-in files by their file name extension: either .xla or .xlam, depending on your version of Excel.
- Delete, rename, or move the add-in file.
- Start Excel. If the add-in was one that was automatically loaded when Excel first starts, you will get a message from Excel indicating that it cannot find your missing add-in file.
- Answer Yes when prompted if you want to remove the add-in file from the list.
- If the add-in was not one that started automatically, choose Add-Ins from the Tools menu. Excel displays the Add-Ins dialog box, and your deleted add-in should still be listed as available. (Remember; this dialog box represents the internal list of add-ins, and hasn't been updated.)
- Select the check box next to the add-in you want deleted. This informs Excel you want to use the add-in.
- Click on OK. You should get the same message described in step 4.
- Answer Yes when prompted if you want to remove the add-in file from the list.

Your problem sounds similar to a problem I had years ago: https://www.excelforum.com/excel-gen...or-add-in.html My solution ended up being to modify the registry location where Excel stores add-in information. See if anything in that discussion helps.
