According to CAL, version 2.0 of BEST Plus is an individually administered, face-to-face oral interview designed to assess the English language proficiency of adult English language learners in the United States. Here are some things that I have discovered during the use of the program and support.
Installing on Windows
When installing BEST Plus 2.0 on Windows 10, be sure that you are using the compatibility mode for Windows 8 to avoid issues during the install. If you forget to do so, you will be told by the BEST Plus installer that the msvcrt40.dll in the system32 folder can not be opened and to check that the disk is not full and that you have access to the destination directory. You can confirm what I am saying by checking the folder and seeing the msvcrt40.dll is not there. If you went online and downloaded the msvcrt40.dll file and wasted time taking ownership to get it to work, please remove it and utilize my installation method.
Removal on Windows
When the BEST Plus program is installed, it does not show up in the Control Panel and therefore it is a bit harder to do a one-click removal. The CAL.org website (at the time of writing) does not show any removal instructions as well so before you start the installation process, create restore points, or clone your drives.
