PSE 23 no longer opens after upgrading to Monterey 12.6.4

[Caroljj53]

I bought PSE 23 a couple of months ago. I only use this to process images. Suddenly, today, after the upgrade to Monterey 12.6.4, it no longer opens. 
Bad timing as I need to process an image to print.

I cleared my Cache thinking that might be it then thought it must be the upgrade.

Any ideas on what I can do? I got ON1 early last year and I do not like it. 

Thanks

Try uninstalling and reinstalling the program.  Otherwise, try contacting Elements support.

Ah I should have thought of that. Thank you!

I uninstalled it, reinstalled it and it now opens and is working.

Cheers
