I have been using PRE for years starting with version 2.0 On my current Windows 7 64 bit computer I have installed.
Photoshop elements 7.0
PRE 7.0
Photoshop elements 9.0
Pre 9.0
Pre 10.0
I now have purchased photoshop elements and PRE 11. I have not installed it yet. I was wondering if I need to remove at least version 7. I have not used it in a while although I am sure there are some files I might need. I tried opening a PRE 7.0 file in PRE 10.0 and it would not open it. I am not running out of room on my system hard drive yet but it is approaching 75%. I store my media on an external drive.
Is there any problem having all these versions on my computer??? Do others have that many on their computer???
