Think-cell in excel stopped working totally with the attached error, excel cannot work until asking to disable Think-cell license. I tried all Microsoft solution here: https://support.microsoft.com/en-us/office/add-ins-and-vba-macros-disabled-20e11f79-6a41-4252-b54e-09a76cdf5101?ns=excel&version=90&syslcid=1033&uilcid=1033&appver=zxl900&helpid=162335&ui=en-us&rs=en-us&ad=us
