Missing archive? Photoshop Elements 9

Thanks for all your comments.  I had also contacted Adobe technical team who sent me links for the .EXE file and the .7Z file and told me to load into the same folder before installing. I downloaded them, apparently successfully, and had to restart the PC so changes could be effected, which I did.  Unfortunately, the restart caused Windows 11 to fail to reboot.  Even after turning off and on again, it still fell over on reboot.  So I repeatedly pressed F12 during a reboot and got to a recovery program that allowed me to return the PC to factory condition which I did successfully.  However, All of the apps and updates that I had previously installed were removed, so I spent a pleasant afternoon re-installing everything - except Photoshop.  It is a salutary lesson to learn that old software may not be compatible with a new OS!  However, my PC is running well again now. 

Thanks again for all your comments. Much appreciated.  I hope this script may prevent someone else having a similar experience.

Best option, get newer software that's compatible with new computers.  12 year old dicontinued software is obsolete.  It's unlikely to work well on Windows 11 even if do get it installed & activated.

there are two files needed for windows' installs.  the installer and the archive (7z).  you need both.

when you start your install, use compatibility mode, win 7.

and you need your serial number and then you need to hope you can still activate.

Please take a look here:

I'll recommend to save the download files on an USB stick, hard drive or CD/DVD, but it isn't sure how long these links are available.  
Many thanks to jim @ prodesigntools.com 

BTW: Photoshop Elements 9 is 12 year old program and not compatible with newer operating system. It's possibile that it doesn't run with Window 11. And it doesn't support the RAW files of newer cameras.

I think you should change to the actual version.
