SU-PQR1618These errors occur because the Microsoft Installer is in the middle of another installation, or has recently performed one and needs to reboot the computer in order to complete it. In order to correct this issue, simply allow the other installation to complete, then reboot your computer and try installing the launcher or editor again. This should allow your installation to complete normally.
SU-BV01This issue can be caused by a few different things. The most common is that you are attempting to install one of our products on a FAT32 formatted drive. At this time, our products are not compatible with FAT32, so you will need to reformat the drive to NTFS in order to successfully install them. Hardware failure can also cause this issue. We recommend checking both your hard drive and your RAM for errors to rule out hardware as the cause of this problem. If any errors are detected in either of these tests, faulty hardware is likely the cause of your problem.
SU-DS01The SU-DS01 error is caused by having insufficient disk space available to perform an installation, which can occur during an update of a game. Updates often require a large amount of temporary disk space to build the new files before replacing the originals.
SU-PQE1223This error is generally caused by one of two things. The first is a prompt requesting administrator access. If you ignore, don't see, or deny this request, the install will result in this error. You should be able to solve the issue in this case by simply uninstalling and reinstalling the launcher. The other possibility is a problem with the existing Visual Studio redistributables on your machine.

The steps required to do this will vary based on your mail client and browser. If you're unsure of how to do this, we recommend contacting your mail client's support team.

LS-0014This error occurs when our system cannot find a file or directory needed to run the program.

If you continue to have trouble or the program is not currently running on your computer, reboot your computer and try again.

0xc000007bOften, this error code is caused by a 64-bit process trying to use a 32-bit dll or vice versa. In this case, the 64-bit launcher is probably trying to load a .dll that it wasn't meant to run with. The problem is that this isn't the only situation that could cause this error code. It could be a subtle problem with any of the binaries used/referenced. All the ways users can get into this state are not presently clear, but usually it has to do with dependencies that are corrupt, modified, incorrectly installed, or that have been tampered with.
