I have downloaded the dutch thesaurus (thes_nl.oxt), in LO 5.2.2. but it doesn't work. It installs, but doesn't show in Writer

I installed the_nl.oxt Dutch thesaurus from OpenTaal. It installs OK (I think) in extension manager, but Thesaurus in Writer Tools stays gray. Right-clicking a word also doesn’t give me any synonyms. What can I do?

For starters, you should better point where you downloaded the extension from.

Did you restart the program? Close all instances of LibO (including the quickstarter, if you use it) and try again. Also check the language settings on your text: on the status bar you can see the language set for the text on the current cursor position.

Confirmed. Downloaded from http://www.opentaal.org/projecten/synoniemen.html and took the 3.x version. Installs fine in LO and AOO 4.1.2, runs in AOO (after some hassles) but refuses to work in LO 5.2.2. Might be a bug in LO, might be something in the file that’s no longer supported.

"The Dictionaries.xcu contains
malformed property key for supported
locales, so it doesn’t work.

(To fix it manually, extract the said
file from the OXT archive, replace all
4 nl_XX tags with a
single one, separating their values
with spaces, like “nl_NL nl_BE …”,
then re-add the corrected file back."

The 3.x version runs in AOO 4.2.0 (developers’ build) without any hassle. It looks like yet another thing broken by LibreOffice developers.
