When launching various gaming programs (usually using the Games for Windows - Live service), the user may encounter a program crash and the error message “Order number 43 not found in the DLL.” In this material I will talk about the essence of this error, list the determinants that cause it to appear on the computer, and also explain how to fix the error “ Ordinal number 43 not found in DLL xlive.dll» on your PC.
Screenshot of the error "Sequence number 43 not found in the DLL xlive.dll"
A little history about Games for Windows – Live
For the most part, error code 43 occurs when working with earlier gaming programs like GTA 4, Dirt 3, Bioshock 2, Halo 2 and other gaming products that use the Games for Windows - Live gaming service from Microsoft. This service, in addition to the ability to purchase games online, allowed you to connect with other users via the Internet, play online games, exchange messages, collect game achievements, and so on.
However, the developer of this product, Microsoft, stopped working with it back in August 2013, although, if desired, the user can download a version of this client and install it on his PC.
The essence of error 43 xlive.dll
The answer to the question “what is error 43 xlive.dll” follows from the text of the problem message itself. This error “Sequence number 43 not found in the DLL xlive.dll” is associated with damage or absence of the xlive.dll library file on your computer, which is responsible for creating user accounts and servicing them with the Games for Windows Live service.
This problematic situation can be caused by the following determinants:
- Random computer crash;
- Using the old version of the GfWL client in repacks of new games;
- Intentional removal of the game client (or xlive.dll file) from the game installer;
- Damage to the client or the xlive.dll library file by viral malware;
- Damage to the Windows registry;
- Accidental deletion of the xlive.dll file by a user.
How to fix "Sequence number 43 not found in DLL xlive.dll" error
So how to fix xlive.dll error 43? Follow these steps:
Video illustration of the solution to the error
Above, I discussed the essence and causes of the error “Sequence number 43 was not found in the DLL library xlive.dll.” In most cases, this error is caused by damage or the absence of the necessary xlive.dll file when launching various game programs. The most effective treatment for this dysfunction is to install the Games for Windows software product; this will help to effectively solve the problem of error 43 xlive.dll on your PC.

DEFINITION
Selenium located in the fourth period of group VI of the main (A) subgroup of the Periodic table.
Refers to elements p-families. Non-metal. Designation - Se. Serial number - 34. Relative atomic mass - 78.96 amu.
Electronic structure of the selenium atom
The selenium atom consists of a positively charged nucleus (+34), inside of which there are 34 protons and 45 neutrons, and 34 electrons move around in three orbits.
Fig.1. Schematic structure of a selenium atom.
The distribution of electrons among orbitals is as follows:
34Se) 2) 8) 18) 6 ;
1s 2 2s 2 2p 6 3s 2 3p 6 3d 10 4s 2 4p 4 .
The outer energy level of the selenium atom contains 6 electrons, which are valence electrons. The energy diagram of the ground state takes the following form:
Each valence electron of a selenium atom can be characterized by a set of four quantum numbers: n(main quantum), l(orbital), m l(magnetic) and s(spin):
|
Sublevel |
||||
The presence of two unpaired electrons indicates that the oxidation state of selenium is +2. Since at the fourth level there are vacant orbitals 4 d-sublevel, then the selenium atom is characterized by the presence of an excited state:
That is why selenium also has an oxidation state of +4.

Tell me what to do in GTA 4 it says serial number 34 was not found in the dll library msidcrl40.dll and got the best answer
Answer from SpRinGtRaP[guru]
What is Msidcrl40.dll?
Msidcrl40.dll is a type of DLL file associated with msdn Disc 2434.21 developed by Microsoft for the Windows Operating System. The latest known version of Msidcrl40.dll is 1.0.0.0, which was produced for Windows. This DLL file has a popularity rating of 1 star and a security rating of Unknown.
What are DLL files?
DLL ("dynamic link library") files such as msidcrl40.dll are small programs, similar to EXE ("executable") files, that allow multiple programs to share the same functionality (such as printing).
For example, when you start Windows and edit a document in Microsoft Word. You need to load the DLL file that controls printing only when its functionality is needed - for example, when you decide to print your document. When you select Print, Microsoft Word calls the printer DLL file and it is loaded into memory (RAM). If you want to print the document in another program, such as Adobe Acrobat, the same printer DLL file will be used.
Why am I seeing errors with DLL files?
DLL files, while shared, exist outside of the application itself. While it provides many benefits to software developers, this separation also opens the door to problems.
Simply put, if Windows cannot load the msidcrl40.dll file correctly, you will receive an error message. Please see "Causes of msidcrl40.dll Errors" below for more information.
In what cases do errors appear in DLL files?
DLL errors, such as those associated with msidcrl40.dll, most often appear during computer startup, program startup, or when trying to use specific functions in your program (such as printing).
Common Msidcrl40.dll error messages
The most common msidcrl40.dll errors that can occur on a Windows computer are:
"Msidcrl40.dll not found."
"The file msidcrl40.dll is missing."
"Msidcrl40.dll access violation."
"The file msidcrl40.dll could not be registered."
"The file C:WindowsSystem32msidcrl40.dll was not found."
"Msdn Disc 2434.21 failed to start. A required component is missing: msidcrl40.dll. Please install msdn Disc 2434.21 again."
"This application failed to start because msidcrl40.dll was not found. Re-installing the application may fix this problem."
These DLL error messages can appear during program installation, while a msidcrl40.dll-related software program (eg. msdn Disc 2434.21) is running, during Windows startup or shutdown, or even during the installation of the Windows operating system. Tracking when the msidcrl40.dll error occurs is important information when troubleshooting the problem.
