What is MSVCR?
MSVCR files (for example, msvcr100.dll) are part of the Microsoft Visual C++ Redistributable packages. Many programs and games, especially older ones, require these files to run properly.

Solutions
Following solutions were tested on windows 10 Virtual machine with 3 CPU cores and 7 GB RAM.

1. Install the correct Visual C++ Redistributable version

There are several possible ways to fix MSVCR errors. First, install the version that matches your system architecture — either x64 or x86. These packages are available on Microsoft’s official website: https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170

Note: The MSVCR file number corresponds to a specific Visual Studio version and release year.

For example: msvcr100 >>> Visual C++ 2010

2. Install both x86 and x64 versions

In addition to the version specific to your device, also download and install the version for the other architecture.
