Hiya. Sorry if this solution has been mentioned before, I don't have time to go through 30 pages of comments.My system is running Windows XP SP2.I was trying to install the Enhanced Edition udpate, with the English language pack, on a clean install of The Witcher from DVD and was persistingly getting the feature transfer error early on while the update was dealing with localized.key.I tried downloading from various sources, and tried disabling both my AVG antivirus, and my Comodo Firewall - no luck.Eventually I did the following:1. Extracted TWEE_Upgrade.exe using Universal Extractor, get it from:
http://legroom.net/software/uniextract2. Placed all three of TWEE_English_language_pack.exe, TWEE_adventure_Side_Effects.exe, TWEE_adventure_The_Price_of_Neutrality.exe into the same directory where "setup.exe" was extracted, 3. Ran setup.exe.Authentication, installation and modification all went ahead with no problems, modification did take some time though.Now all's good
I hope this helps some people.
