This is not the latest patch, but your installation must include this patch (or be Enhanced Edition of The Witcher) in order to apply the newest patch. Versions of the patch 1.4 downloaded before August 2011 will not work.

This links to information on how to upgrade from the original version to the Enhanced Edition of The Witcher. The patch is cumulative and contains all updates included in the previous patches.

File integrity

To check the integrity of downloaded files, one can use an MD5 hash to calculate the MD5sum of the downloaded file and compare it with a known good sum. Below is a table of known good MD5sums (the list will be fleshed out shortly):

Filename MD5sum
TWEE_Upgrade.exe (August 2011)
TWEE_Upgrade.exe (Bad, pre-August 2011)
TWEE_English_language_pack.exe
TWEE_adventure_The_Price_of_Neutrality.exe
TWEE_adventure_Side_Effects.exe
TWEE_Polish_language_pack.exe
TWEE_German_language_pack.exe
TWEE_Spanish_language_pack.exe
TWEE_Italian_language_pack.exe
TWEE_French_language_pack.exe
TWEE_Russian_language_pack.exe
TWEE_Hungarian_language_pack.exe
TWEE_Czech_language_pack.exe
TWEE_EAX_HotFix_2.3.exe

There are many tools that can calculate an MD5sum, for reference one can use the freely available MD5-Checksum by Nero because it lets you specify a known good MD5sum and it automatically compares it with the MD5sum calculated from your chosen file.
