I can't download any version of minecraft. I just get some variation of this error message:

Unable to save download. text2speech-1.10.3-natives-windows.jar

Name: text2speech-1.10.3-natives-windows.jar

URL: https://libraries.minecraft.net/com/mojang/text2speech/1.10.3/text2speech-1.10.3-natives-windows.jar

Error details: Attempting to move successful download to C:/Users\XXX\AppData\Roaming\.minecraft\libraries\com/mojang/text2speech/1.10.3/text2speech-1.10.3-natives-windows.jar

The process cannot access the file because it is being used by another process

Filename on disk: af0c-2512-87d9-2f0c

Path: C:\Users\XXX\AppData\Local\Temp\af0c-2512-87d9-2f0c

Exists: file

I've tried disabling any anti-virus/anti-malware, but it doesn't make any difference. I use Avast, in case that matters.

So, yeah... I appreciate any help.
