What is the windows folder where the standard svg-files are located?
I have looked under C:\Program Files\Inductive Automation\Ignition\data\modules\com.inductiveautomation.perspective\icons , but the modules folder isn’t in the data folder.
What "standard" SVG files? Symbol Factory, the Symbols, or something else?
If you don't have the "com.inductiveautomation.perspective" folder in your modules folder, you probably don't have the Perspective module installed.
