#10027: Packed data verification fail.

[Maulkin]

I just updated today to the latest version and when I attempt to log in from the main screen I am getting:

#10027: Packed data verification fail.

Please restore original packed data files.

 

 

I am running on the standard PC version (not Steam).  I have already attempted to delete everything in the il2/updates folder but after it performs the file integrity check I will still get the above error when I attempt to log in.

This will also happen if I try to log in with "offline" mode.

Have a look here - you might find a solution in one of those threads: https://www.google.com/search?q=10027+site%3Ail2sturmovik.com&rlz=1C1GCEA_en&oq=10027+site%3Ail2sturmovik.com&gs_lcrp=EgZjaHJvbWUyBggAEEUYOdIBCDY1MzZqMGo3qAIAsAIA&sourceid=chrome&ie=UTF-8#ip=1

Thanks Luke I know how to use Google too.  That is why I added in my original post all the common things like:

1) use Steam file verification (I am not a Steam install so this is not applicable)
2) delete everything in the updates folder (I did that three times)

3) uninstall everything and reinstall (I am hoping to avoid this and it should not be necessary.)

I went two pages deep in google and they all say the same three things I listed above, or people go unanswered and the thread goes no where.

Well, if after searching two pages deep in Google you haven't found any other solutions, I don't think you can avoid it. 

 

And yes, it "should" not be necessary, just like there "should" be world peace and happiness. But alas, things happen and files get corrupted. This may be caused by a bug in IL2, a faulty hard drive, Windows acting up, something the user (accidentally) did, or any of a plethora of other reasons. If you've got literally hundreds of thousands of customers, there's always going to be a few of them whose files get corrupted, even though it "should" not happen. In this case, you just got unlucky it happened to you.

I agree with most of what you just said.  The one thing I disagree with is that it is a faulty hard driver or an OS problem.  This would come out when it performs am integrity check, which it performs when you delete the /updates folder.  If that is the case then it would mean the integrity check is corrupt and that is worth investigating.

  I guess I was hoping that someone from support might be interested in debugging this.  I do not run any mods, and I update regularly so this should make it a good baseline to try to understand what is happening.  Based on how many search results are returned on this one bug, you would think this would be a high priority.  Perhaps this is a sign that this sim is reaching end-of-support.

I will consider this matter closed and I will begin the uninstallation.

EDIT:
For anyone else that got to the same place I did (and happen to find this post among the hundreds of other posts about this topic) the uninstall and reinstall worked, but you loose all of your settings and custom keybinds.

First of all, glad to read your IL2 install works again Should you (or anyone else) ever need to do re-install IL2 again, note that you can save your keybindings by copying the data\input folder and restoring it after the re-install.

Well, "verification fail" to me sounds like a corrupted file somewhere, and this "verification" sounds exactly like such an integrity check. Why this isn't picked up by the update program is a different question. I have no idea what exactly happens when you delete the updates folder (being a Steam user); maybe it just checks the file size and/or a version number?

 

Anyhow, if the reason for an error is indeed a corrupted file, this may certainly be caused by a faulty disk or OS "glitch".

Google shows 43 results for error 10027. Across some 300,000 users (steamdb estimates) and 9 years, I'm not sure this classifies as "many"

 

As someone who has worked in IT support for several years, I can tell you that this is not how support works. IT departments are perpetually understaffed and if a customer shows up with a problem that might very well be caused by an external factor (e.g. disk/OS/FS/mods/user actions), unless there's hundreds of users with the same problem, you're usually not going to spend hours and hours to find a cause (which is likely not even possible) or tailor-make a solution by, idk, binary-editing the corrupted bytes. Not to mention the obvious issues with doing that remotely on the customer's computer on the other side of the world.

 

Also, be aware that the forum isn't related to IL2's support department. All of us here are just users trying to help other users It's possible the support department does have a better solution than re-installing IL2, but none of us here would know that. If you want to contact customer support, you can do so by clicking the link on the top-right of IL2's main page

I'll add to this thread as its the second time its happened to me in last 2 years. Can the developers please build a file integrity app that we can run that removes and replaces bad files? Other games do this. Even russian devs know how to do it (see World of Tanks).

 

We shouldn't have to uninstall the whole thing and start over.

[Gryphon_VR]

Fixed with a 51Gb download of everything. I saved the keybindings by using the old 'data/input' folder.

[Maulkin]

Just got the latest update Update 5.505 and it did it again.  This really needs to be addressed.

 Seems like it is enough if it happens just to me twice in just over one year.  I have worked in software development for over 25 years and with any patching system there was always an integrity check.  It is a pretty simple system.

It just happened to me again, so here we go, another 50GB download. This time, I forgot to save the data/input folder with the keybindings, so I am unsure if I will ever play again.

That sucks.

Last ditch effort, if you have some idea what packed files they are (gtp or graphics folder for example, delete only them and the updates folder and try the launcher again. I had mission editor error and it wouldn't start so I deleted only the editor folder in the "bin" folder and ran the launcher and it created a new one and the editor worked again. Maybe a long shot I don't know.

NVM: I left the PC running all night, it downloaded everything, and now I'm into key mapping hell. At least it gives me a second chance to figure out how many profiles I need to create to cover the various classes of aircraft as they have different axes, some have some trims, others not, some have prop pitch, mixture, others don't. If anyone has a good guide to that sort of thing please link me up.
