BUG
The Cell Size Projection Method in the Environment Settings option is unavailable when using ArcMap 10.7 and 10.7.1 in the Japanese, French or Spanish user interface. This is also an issue if versions 10.7 or 10.7.1 of ArcReader, ArcGIS Engine, or ArcGIS Server have been installed.
Inconsistent translation was the root cause.
Replace the XML files with the corrected XML file for corresponding language.
To circumvent this issue, follow the steps below:
C:\Program Files(x86)\ArcGIS\Desktop10.7\help\ja\gp\Environments
Similarly, for ArcReader, ArcGIS Server, and ArcGIS Engine, the paths are:
<install location>\ArcReader10.7\help\ja\gp\Environments\Spatial Analyst Tools.xml
<install location>\ArcGIS\server\help\ja\gp\Environments\Spatial Analyst Tools.xml
<install location>\ArcGIS\Engine10.7\help\ja\gp\Environments\Spatial Analyst Tools.xml
