Razer Synapse 4 Installation failoed message

When I try and start Razer Synapse I seem to recieve a message saying “Installation failed” but it was already installed and running previously.  I click Retry and that doesn’t work. (Nothing happens).

Strangely I received this message 2 days ago, then it went away and was working yesterday and now it’s come back again today.

At the best of times, it’s very slow to start up and I can’t use my macros until it does, so that’s quite frustrating but now it won’t start at all.  I’ve tried uninstalling and reinstalling but that didn’t work.   Also Razer Chroma has stopped working as well with a similar message “Failed to start” and again the “Retry” button brings up a “Downloading” screen which does nothing and then returns to the “Failed to start” message.I’ve posted some more information in the  replies.

ALso, I am running the razer software on another computer and it’s working fine there, so I don’t know what might be different.

Hey there, ​@geoAureolintools360 

Thank you for reaching out. I understand that you are having issues with Razer Synapse and Razer Chroma failing to start, showing ‘Installation failed’ or ‘Failed to start,’ and the Retry option is not working. 

To help me take a closer look and assist you further, could you please send me a PM along with the link where you tried installing Razer Synapse so I can take a closer look and assist you further? Thank you!
