In the article below, we will look into a common library error, tell the reader about rtl120.bpl - what it is, why the file is important for many applications, and so on. We will also present several ways to eliminate the error and establish the causes.

File Description
This component belongs to the category of dynamic libraries from the RTL.bpl category. These files are used by a number of applications that were written in the C++ or Delphi environment. Without the participation of the mentioned libraries, there are problems in the stable operation of applications. This can happen if such files and settings were not included in the compilation of programs. When you try to run such software, you will receive a notification that there is no file called rtl120.bpl. What is it, you know, now you need to fix the problem.
It should also be said that this problem can occur not only with the mentioned library. Other materials with the prefix rtl also fall into this category. Libraries are used in Windows 95-7 operating systems.
How to fix?
We have analyzed the importance of rtl120.bpl, and what it is inin general. Now let's deal with troubleshooting. The most direct and simplest method is to download and paste the file that the operating system complains about. On the Web, you can find resources offering downloads of individual components for the OS. After you have downloaded the desired file, you must send it to the correct directory.
For older operating systems Windows 95, 98 and Millennium, this folder is called System and is located in the Windows directory on the system partition of the hard drive. For Windows 2000, this is the System32 directory, as in new OS versions. However, it is located in the WINNT folder.
For 32-bit operating systems Windows XP, Vista and 7, the library must be copied to System32 from the Windows directory on the system drive. The rtl120.bpl file on Windows 7, XP and Vista for 64 bits is already located in a directory called SysWOW64, which in turn is located in Windows. After copying, restart your computer and try again to run the application that was giving the error.

Causes of failure
The resulting error is already a consequence of the fact that the file with the name rtl120.bpl has been eliminated. What is the effect of malware, not everyone understands. At the same time, malware does not mean viruses themselves, but various “helpers” for cleaning your computer of garbage. Most of these programs only harm the performance of the PC, destroying system files and libraries. If you use TuneUP Utilites or similar software in automatic mode, then be prepared for theerrors and instability of the operating system as a whole.
