# Installation of SAMSON Extensions

SAMSON Extensions are downloaded and installed automatically by SAMSON on its launch.

## I added a SAMSON Extension from SAMSON Connect but I cannot see it in SAMSON

Please check the options below from the top to bottom.

Availability of extensions on different OS
• If SAMSON was launched when you added a SAMSON Extension then you need to restart SAMSON for this extension to be installed - newly added SAMSON Extensions are automatically downloaded from SAMSON Connect and installed on the next launch of SAMSON.
• Please note that not all SAMSON Extensions have Apps or Editors in them which can be seen in the Apps and Editors menus accordingly. Please see Extending SAMSON.
• Check the SAMSON Log by going to Interface menu > Show log. You can filter the log for the SAMSON Extension you have added to see possible issues and whether it has been added to SAMSON at all. If you see the problem (lines corresponding to a SAMSON Extension are colored in red), you can send this log to us with an additional information (your user email and the problem description) by clicking on the Submit button.
