So I had some PC problems lately which led to me having to reinstall my games, and CP2077 is absolutely impossible.

1. Using GOG Galaxy: The installer keeps throwing an endless chain of E9 errors ("GOG.com servers returned an unknown error"). Constantly clicking on "Retry" finally ends with a seemingly "complete" installation after 5 - 20 such interruptions, but the game keeps flatlining with the "corrupted game files" error. Useless. Of course, the "Verify/Repair" option is useless as well because it also throws an endless string of E9 errors.
And no, reinstalling GOG Galaxy doesn't help.

2. Using the offline installer: A complete joke.
* Running the installer without integrity check throws an error that the installation files are corrupt.
* Running the installer with the integrity check active confirms that all files are okay (after re-downloading most of them several times - apparently download servers are as broken as the direct install servers).
And then the installer throws the infamous "Runtime Error (at 500:57): Out of string range." error several times in a row, but continues installing after the error message has been acknowledged, only to end up with another completely unusable install that crashes immediately.

I've googled the usual remedies - use shorter paths, make sure you have enough free space yada yada - nothing. Installing on another drive doesn't help. Shortening paths to ridiculous lengths like "C:\C2077" doesn't help. Shortening the path where the installer files lie doesn't help. Shortening the names of the installer files themselves doesn't help.

This is a frakking joke, and it's a recent problem, because I didn't have this endless chain of problems installing and updating the game even a few months ago.

Fix your damn servers.

Is this a question or a rant, because I cannot tell.
If CP77 was "absolutely impossible" to install, then I would not have managed to do 4 times on different systems, with different patches and without any issues.

1. ALWAYS stay away from game clients - all they want is your data, and offers zero benefits.

2. - An out of string-error comes if the path is longer than 255 characters. You need to clean up your folders if that's a recurring issue.

- If you're having frequent data corruption, you way want to check your storage devices for errors.

- Try downloading the game files from a GoG .torrent. That way you'll get all the files in one go, instead of split files one at a time from "broken servers".

If the latest direct download refuses to install properly, get a torrent from an older version and patch it manually.
That's what I do, because I don't trust the GoG servers at all.
I got 322 GB of CP77 data - installer and patches - offline on my homeserver. And I can install directly from that onto my main system without issues (albeit with some extra delay due to writing from a HDD).

So yeah, find yourself a .torrent, install the game and have fun in Night City!

Rant or question, bit of both, I guess. Just felt I needed to vent my frustrations with a small hope of finding someone who had encountered the same / similar problems and solved them.

As for paths - see above. I shortened them ridiculously.

My drives check out ok, so they're no the culprit. I'll probably give your suggestion a stab. Thanks.

I think the key here in the reply was "Patched".

I have a feeling that person got the game before 1.61 and ran the patch. Because this is Madness!!!

Like the OP, I'm continuously downloading "Damaged Bins" and running the installer. When it finally passes the integrity checks (which takes a Lot of replacing Bin files - over and over, then different ones, then...) the installer goes about installing the game, only to kick up these fricken errors - and I'm just installing to C:\\GOG Games, like GOG has always done

I didn't know GoG offered torrents. Just poked around a bit and couldn't find any reference to them here. It'd be nice to have a way of downloading the installer files all in one go. Where's this handy option hidden away?

I've never had a problem with a downloaded, offline GoG installer. Please check your hard drive. Those go bad way more often than another other PC part and the symptoms of them going bad can be almost anything, definitely including what you're describing.

I've had good luck with software watching the SMART data over the years. SMART's a kinda-failed drive-health-reporting standard that most hard drives have implemented for decades. Some of the data drives supply are things like " "Uncorrectable Sector Count", and "Spin up time" and "reallocation event count". I say kinda-failed because you can't really compare SMART data from one HD to another like the way it was originally intended, but you can absolutely watch a given drive's SMART data over time and pick up on when a drive's starting to get flaky. I use Acronis Drive Monitor for this b/c a friend recommended it years ago and it does the job. Surely there's some better open source stuff out there too.

You sometimes have to enable SMART in BIOS, sometimes per-drive.

But for what you're looking at here, you need a more direct check. Windows's check-drive-for-errors utility is a good place to start.

They don't. As I've described in other threads when there are issues with the official way, the .torrent will be a pirated copy.

It's necessary to do that when for example reverting to an earlier version of a game, since GoG doesn't keep the install files for earlier patches. That's was what I suggested at first as well, but the person insisted there was nothing wrong with the harddrives or anything else locally.

I didn't bother continue the discussion at that point, but I have never had any issues with the offline installers either.

I actually did, for Cyberpunk 2077 specifically. As far as i could tell though, my problem was a tad specific. I was trying to install from the offline installers in an external HDD onto an internal SSD and it kept erroring, saying files were corrupted.
As far as I could figure the read speed was too slow and maybe a little unstable, he GOG Galaxy worked for installing.

I have done something similar, though a long time ago, where the installer files became corrupted during download.

- The files were downloaded to an external harddrive.
- The download went at times so slowly (intermittent server issues), the harddrive went into sleep mode.
- According to the browser, the downloads finished successfully.
- When trying to read the files off the external HDD, some of them were unreadable becase the HDD had timed out during the DL.

In my case, I was using a gen. 2 WD MyBook 1 TB (contained a crappy WD Green HDD), so I fully blame the HDD for the issue I had.

But every time since, even when I DL directly to my home server, through my main computer, I have had zero issues.

Though the HDDs in the server are exclusively Seagate Exos drives (their current Enterprise branding), which are infinitely better than a crappy WD Green.

And I've set the HDDs to never power down in the Windows Power Management settings, which I was unable to do on the old external drive.

Some wild stuff here. I believe strongly that a HD being so slow as to cause issues downloading files or reading files (while installing from them) just doesn't happen. I also strongly believe people like us run into problems like are described here from time to time, but it's a problem deeper than just one HD being too slow or another being too fast.

These problems make me wish GoG published the hashes for their files. SHA256, SHA1, whirlpool, even MD5 - just anything would be fine for file integrity. I'm sure they don't because that's what their integrity check is checking. But hearing about problems like this makes me wish those hashes were published just to get the hash just so we could check the integrity checker.

For what it's worth, here are the SHA-256's for the v1.61 installers:

So... what would someone do with that hash information?

Seriously. I tried for more than 48 hours with no sleep to get the game installed via downloading the install files.

It didn't take long at all to download.

Install Integrity Check kept calling the files damaged. Sometimes I ran it a second time (after many failed attempts) and got different results without changing any of the files - so something's really weird.

If what you're saying is accurate, maybe it is my drive?

That's strange though.

I've encountered this same issue with at least another GOG game, but never with anything else.

I finally ended up using Galaxy, but I wish I didn't have to go that route. Now I'm stuck with all of my junk save games because Galaxy's sync won't let me delete them, and they simply don't seem to exist on my side.

Check it with a hash checking utility. These hashes and checksums have been part of computing pretty much since the beginning for addressing just the problem you're having here - making sure your copies are perfect.

Windows comes with a command-line utility that'll do this for you: "certutil". You use it like so:

c:\download\Cyberpunk2077\>certutil -hashfile "setup_cyberpunk_2077_1.61_(64bit)_(60064)-1.bin" SHA256
SHA256 hash of file setup_cyberpunk_2077_1.61_(64bit)_(60064)-1.bin:
28 cd 6d 25 2f bd 5a 62 5d 2b bf f0 c0 df 88 ea 2a 31 eb 05 79 03 43 ed 0e 42 51 12 83 24 e9 8f
CertUtil: -hashfile command completed successfully.

Note that it takes a minute to run for each of these large, 4GB files.

I use Hashdeep for this. It's a little open source utility over at SourceForge and I've been using it for a very long time. It's a command line utility - I like it b/c it does all the popular hash algorithms, will descend into subdirectories, and it was easy to make a little .bat script I keep in my SendTo folder.

There should be a ton of utilities to do this for all operating systems. I'm sure there are some nice GUI ones out there too. I know the file manager "XYPlorer" will show the popular hashes as a column too.

Sorry for just tossing kinda nerdy techy stuff at you but they're the tools made for the job and it's all I know.

hi, did anyone try with 2.13? I tried using the offline installer and it thown the same error multiple times (install folder was just Y:\Cyberpunk 2077)

it cannot be started, verify and repair in galaxy detects 32gb of files to redownload. Is it possible to install from offline files or not anymore?

With 2.13 after you uninstall delete the folder too (no longer auto-deletes) just to be completely clean.

No issues on my end using the offline installer, I've reinstalled the game so many times (for mods).
