I ran the latest update last night (AMP 126.96.36.199) and since then I am unable to launch the Instance manger and cannot update my Instances. I also tried to run the ampinstmgr upgradeall command from the command line and I get the same error. This was the first upgrade of AMP after I installed it about a month ago on a new VM. I had an issue on the previous one and decided to start fresh. I restarted the server twice after the installation.
The VM is running Windows 2012r2, 2x2.8Ghz processors and 32gb ram. The only other software on the server is Ramdisk and the VSphere vmware tools. I am running as a separate admin user (ampserver). I cannot open the instance manager normally or when run as admin.
Here is a paste of the error I get: https://pastebin.com/E3smKPXF
