Error while saving settings: GNS3VM: Error while executing VMware command: vmrun has returned an error: Unable to connect to host.

Try to run "C:\Program Files (x86)\VMware\VMware VIX\vmrun.exe" -T player checkToolsState "C:\Users\ADMIN\Documents\Virtual Machines\GNS3 VM\GNS3 VM.vmx" in a terminal to see more details.

And make sure GNS3 and VMware run under the same user.

#@Version-Info

#

# VixAllProducts revision mapping

#

# This file translates product version specifications into the appropriate Vix

# implementations.

#

# Each @Version-Info line has 5 white-space seperated entries:

#

#    provider-type: ws, esx, viserver, etc

#    apiVersion: the apiVersion supported, as passed in from VixHost_Connect()

#    ipc-type: none, vmdb, vmodl, cim

#    product-version: the product version string

#

#    implementation-directory: the path to the library that implements the

#          version described by the first 4 parameters

#

#

# The configuration is based on the first 4 fields, which describe

# the product.  The 5th field is the location.  To force it to try

# multiple location, the same configuration can be repeated.  Note that

# list is built in LIFO order, so the latest entry in the configuration

# will be the first used.  If for some reason that value fails, it will

# continue through any other matches.
