Updated to Irfanview 4.50 (from 4.44, I think) through the platform.
Now when I try to open a Sony ARW (raw) image file, I get an error message: "Decode error. Can't load plugin FORMATS.DLL." Updated the plugins with the updater from the Irfanview site, which changed nothing.
– is there a workaround?
– how to downgrade to the preceding version? (Couldn't find it on the Portableapps.com nor on the Irfanview sites.)
Thanks for your suggestions!
OS: Windows 10/x64.
