connector_pane_image
datatype_icon

reference in

Reference to the open registry key.

datatype_icon

subkey

Name of a subkey of root key.

A beginning backslash \ might cause an error.

Default: Empty string

datatype_icon

registry view

Value that specifies whether to delete a 32-bit key or a 64-bit key on a 64-bit operating system.

Name Value Description
Default 0 This node selects the type of key based on the software that is installed. For example, if a 64-bit product is installed, this node deletes a 64-bit key.
KEY_WOW64_64KEY 8 This node deletes a 64-bit key.
KEY_WOW64_32KEY 9 This node deletes a 32-bit key.

Default: Default

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

datatype_icon

reference out

Reference to the open registry key.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.
