Safe Instructions to Fix Windows System ErrorsRestore, Optimize and Maintain PC Performance
I believe many users have the same suffers ---- computer operation goes wrong after you installed a program, while everything is supposed to be normal today.
About error messages like “Missing vs990001.dat.dll” or “vs990001.dat.dll not found”, one thing you can confirm is that this is definitely not the problem of your hardwares or your applications. Such kinds of issue emerge one after another due to the imperfection of system design.

At the beginning, Microsoft developed DLL for its two advantages: dynamic linking and resource sharing, for example ---- Windows has three dynamic linking files: Kemel is mainly for management of memory, process, and thread, etc; User is mainly for user interface and message transmitting; and GDI is mainly for all the graphic plotting and display, etc. of the system.
All functions from these dynamic linking files can be used by any executable file on system. Since Windows 3.1, DLL has gradually become the mainstream of Windows programs owing to its memory-saving feature.
Now you know DLL files are definitely not virus. Read this post and you will learn proper solutions to fix vs990001.dat.dll error.

DLL is a library that contains codes and data used by multiple programs. For instance, on Windows operating system, Comdlg32 executes the functions related to dialog box. So every program can open a dialog box through the functions within that DLL file, which promotes the use of both code reuse and memory.
Through the use of DLL, programs implement modularity, which means they can be composed of individual components. If there is a large online game on your PC drive, putting mass data all in an application, it will take a long time to do the modification. Yet if different codes are respectively put in DLL, the game can be successfully updated without re-installing the whole program.
DLL ExamplesOCX File: Calender control, which enables you to set a date.
CPL File: Every item in Control Panel is a particular DLL.
Device Driver: Printer driver, which sends printing requests to the printer.
When a program uses vs990001.dat.dll, it creates a dependency, which might disabled the program’s normal running if being altered or damaged by others, e.g.:
·Being updated to the latest version
·Being covered (replaced) by early versions
·Being deleted from the computer
These operations are called “DLL conflicts”, which will paralyze the program backward compatibility is not enforced.
If vs990001.dat.dll is replaced, or infected by Trojan virus but failed to be repaired by anti-virus softwares, the following issues may occur:
Trojan Virus RationaleDLL Trojan virus combines a code with Trojan virus functions with some particular ones to write out a DLL file, exporting related API (Application Program Interface), which makes it looks like a normal vs990001.dat.dll file, for example, while the truth is that it carries complete Trojan virus effect.
Some people may be wondering why the producer brothers to make a program instead of making it a DLL. The tedious work is for hiding. DLL will not open a new process when being used, so it is not that easy to be noticed.
The phrase means that programs can’t run normally on Microsoft Windows Operating System due to the problems of DLL’s version or compatibility.

Windows in its early stage didn’t have a strict administrative mechanism, so after installing another program, the original executable ones are always unable to run due to the replacement of a DLL file.
But the program newly installed won’t work either after you restore the original DLL file. And your PC might crash or even fail to launch if you incautiously overwrite a crucial DLL file.
Generally there are two kinds of DLL hell:
Situation One:DLL is incompatible.
For instance, if program A uses DLL file 1.0, and program B uses the 2.0 version (usually it’s because the date of B’s development is relatively later). During B’s installation, DLL file 1.0 is replaced by the 2.0 version. So it is the responsibility of developers.
Situation Two:DLL has its own errors.
The new DLL file has been made compatible, but haven’t been used by A ever before. Who knows whether there is any problem?
In short, it is still extremely difficult to make a perfectly compatible binary DLL file.
Fixing a DLL error could take you as long as hours. It depends on the specific situation.
