I am a longtime user and lover of Calibre and have never had a problem updating to the latest version.
Today I downloaded and tried to install 8.7 but it will not install and I can't uninstall the old version 7.??
Has anyone else had this problem?

Thanks in advance!!
AFAIK there were no OS restricted changes if you were upgrading from a recent previous release.

What OS (brand and version)
What PC CPU (chip)

Security software frequently updates and sometimes causes issues.
