When I try to access *HKEY_CLASSES_ROOT\VisualStudio.cs.10* or any other entry of VisualStudio that ends with 10 I get the following error VisualStudio.cs.10.0 cannot be opened. An error is preventing this key from being opened. Details: Access is denied.
What can be the problem?
Did you start your Visual Studio “As Administrator…”?
EDIT:
See my comment below…
Check the owner of the registry entry.
