Don't use the registry.
Beginning in Vista, access has become more and more restricted because it was abused and became badly bloated. Writing to the registry needs elevated permissions - which means UAE - which is a poor choice for anything new.

Have a look here: Where should I store my data?[^] - it suggests some safer places to store information.

try below code

VB

Dim regKey As RegistryKey
regKey = Registry.LocalMachine.OpenSubKey("SOFTWARE", True)
regKey.CreateSubKey("MyApp")
regKey.Close()

check the documentation of RegistryKey.OpenSubKey Method (String, Boolean)[^]
you need to give true value as writable parameter. otherwise you open as read only mode
