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.
Default: No error
registry view
Value that specifies whether to open 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 version of the software product that is installed. For example, if the 64-bit version is installed, this node opens a 64-bit key. |
| KEY_WOW64_64KEY | 8 | This node opens a 64-bit key. |
| KEY_WOW64_32KEY | 9 | This node opens a 32-bit key. |
Default: Default
reference
Reference to the open registry key.
error out
Error information.
The node produces this output according to standard error behavior.
