Photoshop Elements 2021 won't open on new computer

[philippereichert]

I just replaced my iMac by a Mac Mini with MacOS Monterey 12.6.3. I made a migration of my old HD (Big Sur) but PE won't open. I've got a message saying I should uninstall then reinstall the application (error:11). I uninstalled but now I cannot reinstall it because I don't have my serial number. Apparently I didn't register... So I have downloaded PE 2023. What do I need to do to activate it?

Yes, i've tried that, but when I enter my serial number it says it's already used... (of course it is, by me...)

Purchase a license from Adobe.

Unless you have the PSE 2021 serial number, you won't be able to get the upgrade pricing.

Thanks! I finally found my serial number for PE 2021. How can I upgrade to 2023?

Go here:

and purchase the Upgrade License.

Thank you for your reply. I see I can purchase PSE for $99.99. Is it the price of the upgrade? This is what I paid for PSE 2021...

... Oh, and it seems I cannot make a direct purchase from this site. I am located in Tahiti, French Polynesia. So my question is: how and where can I purchase PSE 2023?

Find an Adobe authorized reseller here:

Thank you, but French Polynesia is not among eligible countries. Will it work if I choose France?

[Peru Bob]

Try it.
