I have exactly the same problem on a 6.1.4300.0 community edition that I have had installed since 2011. I have NO CONTROL over the .net updates on the server and I see there are no hot-fixes for any version less than 7.0.
What am I to do here?
I'm under the impression I cannot update the current community version to anything above what I have without requiring another license, therefore I can't acquire a hotfix.
I desperately need some information, guidance or preferably a resolution here!
Any help is appreciated :)
