Anyone else unable to deploy a registry entry with curly brackets?

I'm trying to deploy a registry configuration to my workstations, but if the value I'm trying to deploy has curly brackets { }, the page just hangs and doesn't submit. If I remove the curly brackets and leave everything else the same, the configuration is created just fine. This is a problem of course because I need the curly brackets.

Has anyone else encountered this? Here's the registry entry I'm trying to push.

Windows Configuration > Registry (Computer)
Action: Write Value
Header Key: HKLM
Sub-Key: Software\Policies\Google\Update
Data Type: REG_SZ
Value Name: TargetVersionPrefix{8A69D345-D564-463C-AFF1-A69D9E530F96} <-- the curly braces here are the problem. If I remove them, the page submits when I click Deploy.
Value Data: 83.

I just had the thought to import a registry configuration file instead of manually entering it in the website. I'll see if that works. I'll let you know.
