I just had the same error (SSMS v17.7) on Win7 x64. After downloading a few times (and I'm blushing as I type this), I realised that I was running low on disk space. Cleaned up, ran again, worked :-)

Worth checking?

I would sometimes receive this error when using an installer we keep in our company drive, especially if there was a possibility of connection issues when transferring the installer to the target machine.

When a reboot doesn't work, using the newest installer from Microsoft works for me. If I get the issue with the newest installer, I download another copy to be sure that there wasn't an issue with the download. For whatever reason, the installer file seems to be sensitive to transfer issues.

Currently, the link to the official download is:
