I am currently running Universal Forwarder 6.6.3 on a Windows 2012 R2 instance. I am attempting to upgrade to 7.1.1, but halfway through the install I am prompted with "The feature you are trying to use is on a network resource that is unavailable. Click OK to try again or enter an alternate path to a folder containing the installation package splunkforwarder-6.5.3...."
6.5.3? That is not installed, I currently have 6.6.3 installed, and am trying to go to 7.1.1, so of course that is not 6.5.3
WTF?
I just got the exact same issue trying to upgrade from 7.2.0 to 9.2.2.
I don't know yet if it's the solution, but we're requesting the 7.2.0 MSI file in order to satisfy the pop-up. In our case, we do not want to risk having a corrupt installation by only deleting the Splunk files.
That's probably one of the quirks of MSI - sometimes it calls for an installation package even when you're uninstalling a program.
why the language?
verify first you have permissions to upgrade.
are you doing it manually? script? tool running the upgrade job?
do you really need to upgrade the forwarder?
in any case, read here all the way through

hope it helps
Not sure what you mean by "the language" -- So I guess I will ignore that?
I am attempting to do it many ways. Via script -- fails, manually using the GUI -- fails. Again, the version I am upgrading from is 6.6.3 -- so asking for a 6.5.3 msi seems odd
This is the command I am trying to run
msiexec /i "splunkforwarder-7.1.1-8f0ead9ec3db-x64-release.msi" DEPLOYMENT_SERVER="splunk-deploy2.XXXX:8089" AGREETOLICENSE=YES
"the language" referred to "WTF?" in your question
try to take a look at the rollback log that your fresh install supposed to provide
