just wanted to follow up and thank you for the help. Turns out it was a browser setting issue. got it fixed and everything downloads normally again. Thanks again.

So is the GOG Downloader going to be abandoned once Galaxy comes out? Would be a shame if it was.

If Galaxy enables you to download the installers, the same way the GOG downloader does, then it wouldn't be a problem. However, yeah, gotta wait to find out if this will be a viable function at all.

When I try to download Brutal Legend through the downloader, I get a message: "Checksum error on Chunk 0. Please contact support". What's that mean?

Short answer, probably a server side error, try again in a couple of hours.

Longer answer. The downloader gets the files in chunks of up to 10MB each. Once a chunk is downloaded, its hash is checked against an xml file on GOG's servers. If the chunk's hash matches the one in the xml, the downloader marks said chunk as complete, and continues to the next ones. If the hash is different, the downloader assumes the chunk to be corrupt, and downloads it again (up to 10 times). If after 10 times it still hasn't gotten a correct hash, it assumes there's a server side error, and tells you to contact support.

Chunk 0 is the very first one, so you may be able to bypass it by downloading the .exe file through the web (2MB?), dropping it in the folder the downloader downloads the files, and see if that works.

Hello! I was just told by a Customer Service Rep that:

In log you are trying to download installer version 2.1.0.22 when new version is available since 18th July as I remember.

I am only seeing version: 1.2 from October 29, 2013 at 2:05 AM available on the website at the following link:
static.gog.com/download/d3/mac-stable/GOG_Downloader_1.2_512.zip

Is there a link to the newest version of the mac client? My version is still borked and now amount of:
1. Redownloading the client and putting it in the Applications folder
2. Removing ~/Library/Preferences/com.gog.downloader.plist
3. Removing ~/Library/Logs/GOGlog.log
Helps.

My copy of Divinity: Original Sin is still stuck in limbo.

Hello,

Does the GOG downloader continue downloading if left on overnight? because mine seems to have paused and continued once i checked in the morning

I think by installer version they mean the D:OS installer, not the downloader one. Remove D:OS from the download list, then add it again and see if that helps.
It should. There is a possibility that it has encountered a problematic chunk and after 10 failed attempts it paused, but I can't recall if it would continue on the rest of the items or not. But I have left it overnight quite often, and it does download as it should.

Thanks for the response. I cannot remove it however. The program freezes on startup every time. I've removed the files the CSR asked and D:OS still shows up and the client freezes before I can take any action...

I've no experience with the downloader on Mac, so I'm not sure what files control the download list. Hopefully, Fallen_Zen should be able to give you an answer soon.

I guess this is as good place as any to ask about changes to the GOG API.

Could you please add a Linux installer node to API response. The current API response is really stupid and trying to get the relevant installers from the response requires hacky workarounds.

Currently DEB packages are under Mac installer node and TAR.GZ archives are in patch node.

edit: fixed

Is GOG downloader compatible with W8.1? If so, should be run in the desktop mode or can it be run as an app?

Are there any plans to integrate Debian (Ubuntu / Mint) Linux downloads in the standard update process? This would be awesome, if you can pull it off -- and I think also a real competitive advantage over Steam Linux.

I do know that you have to protect your download locations and standard apt-get URLs won't work, but it could be done.

How?

You can release a linux version of your gog downloader which acts like an HTTP Proxy for apt-get. The user has to add a http-proxy for apt-get which points to [url=http://localhost:7777]http://localhost:7777[/url]/ where your gog downloader listens. The downloader passes through all requests except a special fake gog download url which just downloads from your standard file server.

For updating / installing the apt-gog-proxy for the /etc/apt/sources.list just provide a regular repository which should be a no-brainer and the configuration / authentication for the games itself is stored somewhere in the user profil.

Perhaps you contact the author of lgogdownloader for using parts of the lgogdownloader for this, this application has already ironed out most bugs.

Waiting for GOG Downloader for Linux...
