How to fix "Can't run app" and "Insufficient memory" error messages

Fix 'Not enough memory' error on your Roku device

System restart your device

A system restart is the least invasive reset method and won't affect your settings. If you have a Roku TV, it is not the same as pressing the power button on the remote or the physical power button on the TV itself.

• Remove the power cord from your Roku device for at least 10 seconds before plugging it back in

If reaching the power cord is inconvenient, you can also use the instructions below to perform a system restart from the Settings menu (assuming you can control your Roku device with the remote or the free Roku mobile app for iOS® or Android™).

In either case, your Roku device will complete a system restart and should return to normal operation after a moment. If it does not, continue to the next section.

How to fix low storage space

Low memory messages may also occur because your Roku device lacks the required storage space to store and install apps. Removing other apps from your Roku device can free up space.

Tip: If your Roku streaming device has a micro SD card slot, you can expand the memory available for installing apps.

How to fix network issues

These error messages may be caused by a network issue preventing your Roku streaming device from properly opening an app. This can be due to a weak signal or issue with your internet provider.
