Fixes for Splashtop Copy-paste Not Working

Copy-and-pasting issues in Splashtop can be caused by a number of issues – often, it’s just a matter of settings, or an error during installation. Pasting as keystrokes can also be a useful workaround if the other steps didn’t work.

The following troubleshooting steps can help you resolve the problem:

Enable copy-and-paste by default in settings

When starting an unattended session with a registered Splashtop streamer, the default behavior for copying-and-pasting is defined in the client options, accessed from “File” > “Options”.

Clipboard sync option for unattended access

Use the “Enable clipboard sync” option to have it on by default. Even though keyboard mapping can be changed in-session, you may also want to change it to “based on this device’s keyboard”, which is less likely to cause issues than basing the mapping on the remote device.

Use in-session settings

There are multiple in-session settings that you can change to try and resolve any pasting difficulties. First off, you want to see if clipboard sync is enabled at all, from the session setting menu.

Second, switch “Keyboard mapping” to being dependent on the local device. On the other hand, if it’s already local, try switching it to remote, or toggling it back and forth.

Switching the keyboard mapping to reset it

Trying different combinations of shortcut settings under “Keyboard shortcuts” can also help. Splashtop shortcuts are also necessary for the “Paste as keystrokes” workaround.

Reinstall Splashtop

You may want to exclude any errors that occurred during the installation of Splashtop and that may be the cause of Splashtop copy and paste not working. The installer can also be used to delete the app by choosing the relevant option. Thus, you only need to download the installer to perform a full reinstall.

Using the Splashtop installer to remove the app

If you still aren’t sure that Splashtop is not being removed correctly, and suspect that some unnecessary configs or registry values are being left behind, the official Splashtop website provides a cleanup script.

Use “Paste as keystrokes”

The in-session options dialogue (the rightmost icon on the bar) also allows you to paste the clipboard contents as keystrokes. This limits you to plain text, but it’s uncommon that you’d need formatting or images in pasted text during a remote session.

Pasting keyboard as keystrokes from the menu

Pasting from a dialogue like this may seem clunky, but that’s where Splashtop hotkeys come in handy. Pasting as keystrokes can be accomplished by pressing Ctrl+Alt+V.

Improve Your Experience with Splashtop

Clipboard sync is an important quality-of-life feature. But other factors can also impact your experience during a Splashtop session, like screen blurriness or lag spikes. To maximize your comfort while providing remote support or doing other remote tasks, visit this Splashtop troubleshooting page and eliminate all the inconveniences that prevent you from having a perfect session.

Why HelpWire Is Remote Support That Works – Not a Clipboard Workaround

Toggling keyboard mapping, running a cleanup script, and pasting via Ctrl+Alt+V are all signs that the tool is getting in the way of the work. HelpWire handles clipboard sync without a settings hunt – copy on one machine, paste on the other, done. It’s free to start and runs on Windows, Mac, and Linux with no reinstall.
