Updating Visual C RuntimeMicrosoft will occasionally update the C runtimes as part of their automatic update. If the Previzion build was compiled with a later version of the C runtime than the build on a system, executing Previzion will fail with a message indicating that re-installing the application may fix it.
The correct fix is to install the most up to date version of the C runtime. Once downloaded, simply execute to update Runtime.
You may download the latest version of Microsoft Visual C Runtime from our Download Dashboard.
