When installing MapSAR on a computer using Windows 7, an edit needs to be made to the installation file prior to running. In the tools folder, right click on ~LoadMapSARTools_Win7.bat and select Edit. This line,
copy c:\mapsar\tools\aaloaded.config C:\users\%username%\AppData\Roaming\ArcGIS4LocalGovernment\ConfigFiles\loaded.config /y
should have quotes around the command. The correct line should look like this:
copy "c:\mapsar\tools\aaloaded.config C:\users\%username%\AppData\Roaming\ArcGIS4LocalGovernment\ConfigFiles\loaded.config" /y
Add the quotes and save the file. When ready to install the MapSAR tool set, double click this modified file. If you already ran this file, its OK to run it again.
