Good afternoon Alan and welcome back!
Thank you for reaching out to us.
We are sorry to hear about the struggles you have been experiencing while attempting to upgrade our the Events Calendar Pro add-on. I would love to help you with this topic.
Normally, this process is seamless. I am not sure why the installer is stopping on your site because the folder already exists.
Another workaround that might solve this for good (for the next update) is to:
- Deactivate Pro and Delete it completely
- Install a fresh version from the Downloads section (using the .zip file).
I have a hunch that a brand spanking new install should clear this type of issue.
Let me know how that goes.
Best regards,
Geoff B.
