When running the neoTextil Installation Wizard and if Adobe® Photoshop® is not installed on the default location, then the Photoshop icon will not appear. 

To proceed with the installation, chose the custom directory installation option to select the Photoshop destination in the neoTextil installation process.

Once clicked it shows new fields below and allows selecting the application path from the buttons next to the fields. When the application path is selected, then it will fill out the path of the plug-in automatically. If the path of the plug-in is different, then another one can be selected from the button next to the fields.

You have reached the step of the installation progress. The new version of plug-ins, panels, and user data will be installed. Previously installed neoTextil plug-ins and panel versions will be saved as backup.
