Just noticed this today when creating configs through configure feature.
Any body know how to fix this missing properties.txt so i dont get this error msg
Running 2015 Sp5
Ended up working out that custom properties file location was pointing to ProgramData/solidworks/solidworks 2014?.
Which i had recently uninstalled.
Had to delete old file location and put in 2015 one shown here.
Find file properties.txt and copy it into expected location (see SW warning).
