Now I know this has been covered in numerous posts, but still I don't have a solution. I'm trying to install the EE for the original witcher. I have verified the checksums of the downloads, however the universal extractor will not extract the exe. Something about a corrupt file.I have now downloaded the upgrade 9 times or more from different sites with no luck.Question: What does the upgrade icon look like when you download it? Is it a windows system icon or a witcher wolf head? (I'm getting the system icon)Even though the upgrade was verified it seems to me to be missing something. The error is: Feature transfer error Censored Catastrophic errorThis occurs after hanging on localized.key on the install. I have tried everything in the FAQs. Tried compatibility mode.Bought this in Canada if it makes a difference. I've read that some people have got it working for them...HOW? Update registered fine.Thanks for any help.OK got it working. I'm a idiot. I thought the extractor hung after finding the corrupt header and I exited it. Just had to give it time to do its thing. DUH!
