MSI wont install

So, I'm not sure what the issue here is. I've got a MSD that I've created using this bat file to copy a file down to a local machine and execute it.

The folder is created, the files are copied and the return code says it ran...but it's not installing! I can run the MSIEXEC from a command line as is, and it installs just fine.

Am I missing something here?

Here's the .bat

Echo off
mkdir "C:\Drivers\FILE"
Copy "FOLDER\*.*""C:\Drivers\FILE"
msiexec /i "C:\Drivers\FILE\applicationname-win64-installer.msi" SHOULDAUTOUPDATE=1 /qn
