Virtual printer error after upgrading to VMware Workstation 12.5.6

Hi, I have just upgraded to VMware Workstation 12.5.6 on Windows 7 64 bit: when I start a virtual machine, I get this error:

"serial0: Unable to launch virtual printer proxy"

I found a similar topic here:

https://communities.vmware.com/thread/518809

but the suggested solution (add printers.enabled = "TRUE" to "%programdata%\VMware\VMware Workstation\settings.ini") doesn't work.
