Reply to All: I followed Leigh's instructions--RAW files--right-click--download etc. The files were saved in the default folder. The file types were both .txt, but no file was appended with a .txt extension in the default folder. I restarted the application, opened Text / Spelling / Check Spelling, but I still got the same message ("Unsupported languages. Document contains languages (en-CA) for which no dictionary is installed"). So I deleted the files and installed Leigh's files. One file type was saved as an AFF file. The .dic file was saved as a txt file and I had to add the .dic extension in the default file (ProgramData / Affinity / Common / 1.0 / Dictionaries). And again, the same "Unsupported languages" message appeared after I restarted the application and tried to use the spell-checker. Admittedly, I'm a user with less experience at such things, but, after several attempts, if I'm still doing something wrong here, I don't know what it is. Thanks for your help.
