Hi Experts,

Can you please help point me in the right direction? How would I go about in troubleshooting the XLAM "Is Not A Valid Add-In" error?

I already set the isAddin = True and using FileFormat:=xlOpenXMLAddIn.

What else could be wrong?

Many thanks in advance

I got rid of the error by unlocking the workbook before the installation process.
