Failed to open descriptor file

[rforkner1]

I don't know if anyone else is experiencing this with week 96 update, but can't even play game at all. . Week 92 update gave me a headache, and now this it took me a week to fix my computer after week 92,

Every time I try and launch game from steam I get this message : Failed to open descriptor file ../../../Icarus/Icarus.uproject why are you guy messing round with my system files. Oh have steam on one drive and the game on another which I had to get due to sheer size of this game. So what is going on here? anyone in English please I don't read any other language;) Anyone know of fix for this? I've gone through file checking and all that and no problems there, I'm at a loss to where to look now.

I understand that you have already done Verify game in Steam.
1) Please take a screenshot of the error and post it here.
2) Have you tried running the game from your desktop? (considering that you write that launching from Steam occurs with an error)

3) Your PC specs, OS, subversion (21H1,21H2)? DX11 or DX12?
Do you play on experimental branch? GeForce now? Virtual machine?
Are you running the game or Steam as administrator?
Is your Steam in 'offline' mode?
Do you use or have previously used mods?
Write down everything that makes your game different from normal conditions.

4) How much free space do you have on each partition where the OS and the game are located?
What antivirus do you have installed?

How did the game get to the other drive ? Did you add that drive as a library to steam and then install it or did you just copy/move it ?

I am having issues posting the screen shot in here. I don't know how to get my screen shot to post. As far as launching from desktop, no I haven't.

as far as OS: Windows 10 version 22H2 64bit, memory: 16Gb CPU: AMD FX-8120 Eight-Core Processor. 0 mods just only DLC. No I do not play on experimental branch. No I do not run as administrator, steam in online.
I am running Kspersky anti-virus. An no I'm not going to disable it just so you can infect my computer.

What makes it different I can't even play game all so how can I tell if there is any difference?

As far as free space about 50 Gb is left, that is why it was installed onto a different drive is because I know there wasn't enough free space. So I got the larger drive dedicated to games, I Really don't know what more I can say other than I'm to the point to ask for my money back on this game especially if with each update you guys screw my computer up.

1) There is always a huge amount of free image hosting. I assume that you get a white rectangular window with a similar error.
2) { As far as launching from desktop, no I haven't.} Well, try it! Well, it’s not me who will do it in the end. I shouldn’t ask you to do this additionally, should I?
Although the result will almost certainly be the same, it still wouldn’t hurt to check further.
2.1) Check the launch from the shortcut - write the result here.

Your error is not related to either Icarus or Unreal (it’s too typical). This was clear yesterday, but it didn’t stop us from checking a few more versions. You can type this search string into Google yourself (unreal failed to open descriptor file). You don’t have to read everything related to the Unreal editor.

----------> {AMD FX-8120 Eight-Core Processor} The CPU is so old that I'm not sure if it supports all the required instructions for Unreal 4.26 It also simply does not meet the minimum CPU requirements on the Steam store page Icarus.
However, it was also not by chance that I asked you about the amount of free disk space and antivirus, because strangely enough, for these reasons this error can also occur.
3) I also have KIS. It’s just that there have already been several complaints about Avast, to the point that it generates an error (Error 051). Therefore, it won’t hurt to know which antivirus.
I understand that you have KIS, and not, for example, KAV (these are different things).
3.1) Write here exactly which version of Kaspersky you have.

4) As far as I understand, you have 50GB free on system drive C: But you did not indicate how much on the partition where the game is located (sorry, but I shouldn’t constantly persuade you to provide information about your PC)
The fact that your game is on a different partition (not on the system drive) is absolutely normal, this is the case for me myself.
I assume that on the partition where Icarus is installed you have at least 100GB free space.
4.1) If this is not the case and you have less, then write how much here.

TOTAL: you have a problem with your PC. No one is ruining your PC, you can certainly refuse the game. Only an error like “failed to open descriptor file” is a system error and has nothing to do with the game (you can look it up yourself via Google).
Considering that you have a very old CPU, I can’t give any guarantees for anything.

1) To begin with, in such cases they advise (I’m not sure if it will help, but it won’t hurt to check in any case) {Prevention - to exclude trivial causes}
https://support.microsoft.com/en-us/kb/929833
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
Based on the test results, everything should be fine.

2) {This is a prime candidate for your error}
We update Visual C++ (too much depends on it now)
ONLY from the official website (select your language yourself)
https://learn.microsoft.com/ru-ru/cpp/windows/latest-supported-vc-redist?view=msvc-170
https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170
AND (don’t ask me why, because it’s too long to explain and translate) it will be necessary to install both the x64 version and ! x86 version (BOTH), despite the fact that everything seems to be on x64 now. If the system refuses to install the x86 version, then don’t (this is unlikely).
https://aka.ms/vs/17/release/vc_redist.x64.exe
https://aka.ms/vs/17/release/vc_redist.x86.exe
latest version 14.36.32532.0
(sometimes due to the fact that you do not have the latest version of Visual C++, the latest versions of gpu videodriver behave inappropriately)
AND THE MOST IMPORTANT: please don’t tell me that “you have the latest Windows updates” because the updates don’t arrive there. This is a separate package, and more importantly, sometimes it happens that Windows updates themselves break the work of this library package.
During the reinstallation of Visual C++ Redistributable, you MAY be prompted to “Repair” several times - be sure to agree and click on it {this is the main part of these steps}.
Installed and rebooted.
Check the game to launch from the shortcut on the table. Write your result here. Then check the launch from Steam.

3) In theory, point 2 above may be enough, but to be sure: make sure that you have the latest version of Microsoft .NET Framework 4.8.1 (I’m not sure that it will help, but it won’t hurt to check in any case) {Prevention – to exclude trivial causes}
https://dotnet.microsoft.com/en-us/download/dotnet-framework
Web Installer https://dotnet.microsoft.com/en-us/download/dotnet-framework/net48
Offline 4.8 https://support.microsoft.com/en-us/topic/microsoft-net-framework-4-8-offline-installer-for-windows-9d23f658-3b97-68ab-d013-aa3c3e7495e0
By forcibly reinstalling this package (internal checks will occur there). Best (for me) -> Web Installer (in this case it should always ‘pick up’ the latest version)
During the reinstallation of the .NET Framework, you MAY be prompted to “Repair” several times - be sure to agree and click on it {this is the main part of these steps}.
After that, reboot.
https://www.microsoft.com/en-ca/download/details.aspx?id=30135 (.NET Framework Repair Tool is a check-repair) This is important if, for example, some registry settings and the like have gone wrong. So make sure that you have the latest version of the .NET Framework and then Repair. Then reboot.

4) Disable memory compression windows 10 {Prevention - to exclude trivial causes + will reduce the likelihood of potential lags} (will not interfere with stability, including in other games)
The first link is from Google (under no circumstances should you download anything - there is a visual aid there)
https://www.elevenforum.com/t/enable-or-disable-memory-compression-in-windows-10-and-windows-11.3555/

Having completed 4 points above, we check the game by launching from the icon on the desktop (DX11). Write the result.

This is frustrating me to no end, and you have been a great help in figuring this out. I feel as though that I can play this game with only couple problems that has risen since buying for over 900 hours and now all of a sudden your telling me that my processor is the problem. I know its and old computer but I don't have money to just throw away like this. I've played the game for 935 hours and your last update screwed everything up. So don't try telling me its my computer, you guys changed things and now the game is unplayable. This is bad business, oh here buy our game for way more money than its worth then you start using whole new instruction set, and the game is unable to run now. That has nothing to do with my computer. I feel as though I've been a victim of bait and switch here with this.

1) I didn’t tell you to throw away your PC, I myself have an i2600K (look at what year it was made). And I also don't have money for a new PC (not at the moment) because I'll have to change the entire platform.
I'm just telling you like it is.
2) Developers cannot change anything, because the executable file is compiled by the Unreal 4 engine. What is predetermined there - so it will be.
3) {This is bad business, oh here buy our game for way more money than its worth then you start using whole new instruction set, and the game is unable to run now.}
This claim is unfounded, because the minimum CPU requirements are stated on the Icarus page in the Steam store. What do the developers have to do with it?
4) Everything you write next is completely unacceptable. So it turns out that you know that your PC does not meet the minimum requirements, you buy a game, play it, it stops working, and then it turns out that someone else is to blame?

PS The most important thing. Have you done any of what I wrote?
Have you checked launch from the icon?
Have you checked Windows?
Have you reinstalled Visual C++ Redistributable?
Have you reinstalled the Microsoft .NET Framework?
