Photoshop 5.5 can't launch anymore in Windows 10-not enough ram
Tonight I tried to open a photoshop file on my windows 10 enterprise pc. It kept saying not enough ram to launch. I ran windows memory test and no bad ram was found. I've used this version ot Photoshop on different pc's with different windows OS's over the years and haven't ever seen this problem. I had LibreOffice, Explorer, Notepad, and maybe more apps running. I've used Photoshop occassionally on this pc and had no problems. I have an hp desktop with 1tb drive, 8gb ram, 64-bit OS, x64-based processor, hp monitor (1600 x 900). The main apps I use include Norton Security online, LibreOffice 6.2, Firefox Quantum, Quicken deluxe 2009, Epson cx7400 printer and scan. My system does regular updates. Any ideas? Thanks.
