A corrupt .registry file exists at {0}.
Open this file in a text editor, and remove/escape any characters that
are regarded as illegal within XML strings not surrounded by CData.
These are typically the characters &, `<`, and `>`. Again, this
is an XML document, so you will see many < and > characters, so just
focus exclusively in the string values not surrounded by CData. Once
these have been corrected, rename the .registry.bad file to .registry.
Once saved, try running the same Chocolatey command that was just
executed, so verify problem is fixed.
NOTE: It will not be possible to rename the file in Windows Explorer.
Instead, you can use the following PowerShell command:
Move-Item .\.registry.bad .\.registry
