NewYears1978: I don't think it autoupdates to 1.1.
People keep saying that..but when I reinstalled it did a patch but it wasn't 1.1
I know this because the DLC didn't work, until I manually ran the 1.1 patch, which it did allow me to install. Had it already been up to date it would have said so.
Aspenwood: Gonna try posting this again, as my first one didn't seem to go through.
There seems to be a difference between GOG and retail, as GOG version came with the day one patch (read: without having files necessary for playing removed from the DVD), and thus did not require verification. Therefore people with GOG version can roll back to 1.0. However, people who have retail (like me) are screwed, as the retail edition required the day one patch (verification) to get to 1.0 and be able to play; because you cannot play the retail edition of the game without updating, there is no way to get to 1.0 anymore, as it does not exist as an independent download (as far as I'm aware), and the patcher automatically goes to 1.1.
Yes there would be a difference. Technically the GOG build would have actually be done LATER than the DVD as GOG.com allows instant distribution on release day so the "day one" patch could be compiled into the build plus GOG had the added advantage of being CDPR's SISTER company so a strong relation existed allowing them to do builds quicker than anyone else I would guess.. DVD's take time to ship to distribution and reseller points so the build would be older and therefore didn't have the day one patch in the installer.
I'll give CDPR credit in this regard: they appear to be sincerely listening. So I suggest to get a few of your fellow "victims" put a few posting here and on the public form asking for the day one patch for retail as a separate build. They are more likely to do it I think now that the SecuROM is removed in patch 1.1. Given that, if I had purchased the DVD (which I wouldn't do because of the DRM), I'd stay with the 1.1 patch as the SecuROM takes CPU cycles and FPS. Overall consensus is that the OFFICIAL 1.1 patch (not the premature accidentally released one) in the majority of cases didn't make anything worse (and probably made non-working quests doable), I would try to reinstall again in the followng manner:
1. Run the installer
2. Delete ALL folders and files left by the program. If you aren't sure where they are, try c:\program files\ using your file explore and find the place where it is stored. You can also search for the folder name "CookedPC" which should belong to the game. Delete any folders/files appearing to relate to the game. (parent folder should be (name of drive)\program files\.
If you are well versed in editing the registry you may want to remove any registry entries related to the witcher located in the HKEY_LOCAL_MACHINE\SOFTWARE section and/or the HKEY_CURRENT_USER\SOFTWARE sections before you reinstall. when I am in doubt and want a clean install I try to remove EVERYTHING the program leaves behind so I'm sure its really clean.
Then I suggest disconnecting the computer from the Internet before reinstalling to prevent the auto updater kicking into play and applying stuff automatically thay may interfere with patch being installed manually. (the 1.1 patch I think assumes a CLEAN install), and apply the patch manually. Then reconnect to the Internet if you wish and get any DLC you haven't backed up or downloaded yet. Since SecuROM is removed in Patch 1.1 you may not need to activate.
Hope this helps.
