PROBLEM
With ArcGIS License Manager 2021.1, on most localized language operating systems the License Manager Reference Guide opens in English and not the local language.
Chinese Traditional (Taiwan), Chinese Simplified (PRC), and Portuguese-Brazilian languages should not be affected by this problem.
There is an incorrect link to the appropriate language-specific documentation directory.
