In some operating systems at start of the program the message is issued: "This application has failed to start because MSVCR71.dll isn't found. Re-installing the application may fix this problem". It means that in OS the Microsoft .NET Framework Version 1.1 Redistributable Package is limited to operate because of MSVCR71.dll library is missed or corrupt (Microsoft Visual C Run-time, version 7.1).

In that case you should install this package, loading from direct link http://www.microsoft.com/en-us/download/details.aspx?id=26. Downloadable file is named Dotnetfx.exe, run it on your computer. Another solution is to load library MSVCR71.dll from the entrusted source and to place it in the subdirectory of the program (in an example – D:\CheckLog), however such decision is less reliable. But for 64-digit versions of an operating system, alas, it is necessary to use it.
