  1. Hello,

    I recently purchased a mouse(Deathadder wireless) and I cannot get synapse 3 to install on my machine.

    I run the installer and select the synapse 3 install(no cortex) and I receive the following error:

    Installation failed with error code: 121

    This error has persisted through changing the install location, changing the install drive, trying to install Synapse 2(This told me I lack permissions).

    I kind of suspect this is a windows permissions error for synapse 3, but I have administrator rights on this machine and I have full permissions on this drive. I did transfer my system/windows/files to a ssd drive several months ago, but when I test download other programs I can successfully install and uninstall them fine. What does this error mean and how can I fix it?

    Hi there! Thanks for initiating this thread. Are you using a personal computer and connected to a home network? Try isolating the behavior by creating another local Windows user account by following the steps below:

    1. Select the Start button, then Settings, Accounts, then Family & other users.
    2. Select Add someone else to this PC.
    3. Select, I don't have this person's sign-in information, and on the next page, select Add a user without a Microsoft account.
    4. Enter a user name, password, password hint, or choose security questions, and select Next.

    Note: You can delete this account once you've done testing it with Razer Synapse 3.0.
