This new change does concern me and I am holding off on any more purchases until there is clarification from GOG. I am a Penguin and I don't want to have to have an actual Windows installation just to install the games I want to play. I also like to use the data files for some games under Android, like the ScummVM compatible games. I hope this gets worked out soon.

They could at least get the /nogui working again so the installers would work in Wine (maybe?).

Or better, a CLI option to extract the installer.

In his last post Gowor said he was working on it.

I think it might be a tricky fix seeing as the bug only happens on some setups.
I for one can run the new installers through WINE. It gives me a few (seemingly harmless) warnings at the end, but the data extraction works fully.

Tested on a Debian Sid amd64, with WINE 1.6.2, without the /nogui switch.

I would welcome this with open arms!

One very good use for the possibility to extract the installers is that they can be checked, now that there's no proper downloader with hash checking for linux (I remember something about the lgogdownloader not working for all titles after the new site launched?). Hopefully Galaxy client will do that once it arrives, also for Windows installers in Linux.

I've had some downloads go corrupt and I just checked my whole downloaded library with wine innounp.exe paired with find command (innoextract -t option didn't work, the whole thing just freezed when it found a corrupted installer).

which game was that? any particular settings/installed programs? I get the error with wine 1.6.2 as well.

hmm, or is the "runtime error"-popup message that I am seeing, the "harmless warning" that you are describing?

That is very understandable, but on some Linuxes it would greatly help to have the ability to tamper with the game data. As long as it would be clear that any result is totally out of GOG's responsibility this would be a benefit to the users.

Good that people here could extract the password. Only you could have published it right away and make it a bit easier for everyone. ;)

Has anyone noticed if the new packing method is spreading?
I saw no official post regardig this issue, thus I'm wondering if GOG is waiting for the alarm to wear off and persist on the same track, or they are rethinking their strategy while paying attention to their "special" users and core values.

That is an excellent point. GOG is not providing me with the service I want for most of my purchases, they actually never did, I have no reason to complain (except my own foolishness) and since i'm unwilling to go through the only officially supported path (find a machine running windows, install there the thing and transfer back the required files) i should just stop ruining your fun.

Another excellent point, I never assumed I was probably breaking the law by tampering with the installer, the new TOS just makes it clearer. Again, no reason to complain on my part, actually I'm the one that should probably make an apology, and i certainly won't repeat my mistake. Ever.

Nothing says you can't use innoextract. It doesn't circumvent anything and doesn't tamper with anything. It doesn't even reverse engineer anything - innoestup is an open tool. EULA says nothing about prohibiting it, it's clear fair use and etc. etc. However vaguely DMCA-1201 and the like are worded, they are talking about DRM, and innosetup packages aren't DRMed.

However bypassing a password is a completely different story.

I’ll have to check next time I have access to the computer hosting my GOG library. It worked with a clean WINE prefix, nothing installed before the game itself. Might be, I can’t remember the exact error. A couple error messages (maybe just one) near the end of the install completion.

Sorry for wanting some recap, but this will affect direct unpacking only, or would it prevent Wine or PlayOnLinux from installing the games properly as well? There's been a lot of discussion, and I'm not sure if this point has been refuted or confirmed.

In principle this was a breach of GOG user agreement.

9. WHAT YOU CAN'T DO WITH GOG SERVICES
(c) Don't hack, harm, grief or misuse GOG services or GOG content.

I like that you see it actually quite relaxed but in principle GOG reserves itself the right to terminate the customership of people who want to see what's in the installers. And all this only so that support has a bit less to do. A simple: don't do it unless you know what you are doing and then you'll be on your own, might also been enough.
