i have a HP all in one that i just purchased and it wont let me install adobe elements 10

If your computer lacks a CD/DVD drive for installing software disks, you can purchase an external optical reader on Amazon.

PS Elements 10 from 2011 wasn't built for modern operating systems. It might work, or it might not.  

Since you have invested in a new computer, this might be a good time to upgrade your software, too.

Photoshop Elements 2025 (3 year license).

Two ideas that MAY work to install and/or run old programs in Windows 10 or Windows 11
-RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window
-and/or select Run as Administrator to assign FULL Windows permissions

Teena, what error do you receive when installing Photoshop Elements 10? Are there any scratches on the CD that contain the installation software? What version of Windows is running on your new HP All-in-one? ^JW
