Consider the solution to this error and explain the reasons due to which it appears. The problem is especially relevant when installing one version of the platform instead of another. For example, from 1C 8.0 to 8.1 or 8.2 to 8.3. Often occurs when creating a new database, and after installing the program.

The reason is in the settings of the 1CEStart.cfg file (the approximate path to the file is C:\Users\<ИмяПользователя>\AppData\Roaming\1C\1CEStart). This file is required if the platform is launched via the 1cestart.exe file. “The installed version of 1C enterprise was not found” means that the wrong value is written in this file. This happens most often when changing the 1C platform from 8.2 to 8.3.
