Camera Raw ver. 188.8.131.527. I have never used Bridge, so I don't know, but I never needed to use Bridge to open my RAW images previously. I have restarted the computer since the PS installation. The RAW images will open in Lightroom, but this is also a program I rarely ever use.
Of interest, I have a Laptop running Windows 10 and PS ver 21.1.2 with Camera Raw ver 184.108.40.2067 which does open the RAW images. I tried installing this combination on my desktop but PS still locks up. I have also downloaded a version of DNG to the desktop CPU, but attempting to open the DNG images also locks up the system. As I stated, once PS locks up it can only be closed by utilizing Task Manager.
Thanks for your response. Any additional ideas or fixes will be appreciated.
