This (mainly french) project has shutdown in 2015 as I can read on Wikipedia: https://en.wikipedia.org/wiki/Combined_Community_Codec_Pack
On Archive.org ( https://web.archive.org/web/20200823190307/http://www.cccp-project.net/ ) I found the original download host, and it is still up, here are the links:
32-bit: https://kuroko.fushizen.eu/cccp/Combined-Community-Codec-Pack-2015-10-18.exe
64-bit: https://kuroko.fushizen.eu/cccp/Combined-Community-Codec-Pack-64bit-2015-10-18.exe
I think that Crossover should host these files because this codec pack was the best in the 2010's.
