+??? bug "Installer Permission Problems"
+    
+    ^^Description^^
+
+    During installation of a product a "Windows Permission Error" with the error code EPERM shows up and the installation is aborted.
+
+    ^^Root Cause^^
+    
+    Sometimes the permissions of the community folder are set to not allow the current user to install addons in it.
+    This might be set since the installation of MSFS or MSFS might have changed it at some point.
+    
+    ^^Possible Solution or Workaround^^
+
+    One of the following solutions usually lets the desired addon be installed
+
+    * Check the permissions of the community folder and correct them.
+    * Rename the current community folder, create a new one with the same name and move your installed addons into the new community folder.
+    * Start the installer with admin permissions.
