There are a few items that may cause a Registry element to not process correctly.
The first item to check is to verify that the Registry element Validated.
If an element does not validate, it will not process.
The best way to verify this is to review the sltrace.htm log file on the affected system.
This log file is located in %temp%\Desktop Authority
If the element validates, the second item to check is to see if there any error messages or additional information in the sltrace.htm log file that may be relevant. It is possible this information may indicate a permissions issue when writing or deleting from the registry. It may also show that the Key path is invalid. Any information on the processing of this element will be listed in the log file at the timestamp the element validates.
If the Registry element validates, and there is no relevant information in the sltrace.htm log file, the third item to check is element syntax. Please review the element and verify that all settings are correct, and in the proper upper/lower case.
Registry element syntax issues that may be a factor include:
Action: Verify that you want to act on the Value or the Key. They are different. In the registry editor (regesit.exe), a Key is in the left-hand pane, while the Value is in the right-hand pane.
Hive: Verify that the correct Hive is selected. If writing to HKCU, verify that the user can manually process this task. If not, then DA will have the same issue.
Key: Think of this field as the path to the Key. However, it neither begins nor ends with backslashes (\).
Type: If acting on a Value, verify that the correct Value type is selected.
Value: This is the name of the registry Value listed in the right-hand pane of the registry editor.
Data/expression: This field refers to the contents of the Value being acted on. Normally this is listed in Decimal format to make it easier to review. However, it can also be listed in Decimal view to confirm with any documentation that is used as a reference.
‘Force use of 32-bit registry locations on 64-bit operating systems’ is unchecked by default. We recommend using the correct explicit path when defining the Key field.
Finally, remember to ‘Confirm’ the changes to the element.
