While downloading, some browsers may change the file extension of the Yasai.xla file so that it is renamed Yasai.xls. If this occurs, manually rename the file to Yasai.xla before installing.
This version is compatible with all Windows releases of Excel since 2003, and Mac Excel 2011 and 2016. Histogram charts are not available on Mac Excel 2011 due to an Excel bug, but all other functionality is largely identical between the two platforms.
