Hello all. When I attempt to view a project or open a project in the designer it gives this error: `LookupError: no codec search functions registered: can't find encoding 'utf-8'`  
This is a new install of 7.7.2, it was working on 7.7.0 and I did an upgrade and now even if I make new projects they won’t open. I have uninstalled and reinstalled Ignition. This is a dev laptop and I am learning about ignition. I have installed all the modules necisary for the ignition demo app and attempted to load the gwbk for the inductive university “Devices in Ignition” section. Unfortunately I am not absolutely where it stopped working, I think it was back when I did the upgrade to 7.7.2

Windows 7 64 bit, jre1.8.0\_25, MySQL and MSSqlServer.

It was probably a rookie mistake on my part, if anyone has any ideas I would appreciate it.

Error:

[code]LookupError: no codec search functions registered: can’t find encoding ‘utf-8’

a couple more things to try:

remove any cached webstart apps:  
javaws.exe -uninstall

Delete ignition user folder:  
C:\Users[i]{userName}[/i].ignition
