This validator applies only to major upgrades.
To perform this validation test, the validation engine compares the latest installation to an earlier version of that installation.
Corrective Action
To find where the value of the Action property is entered, open the Upgrades view. Select the major upgrade item, and then click the Advanced tab. The Detect Property value is used for the Action property.
Note:Note the following:
| • | The property is public if it is in all uppercase letters. |
| • | The property is unique if it is not shared with any other major upgrade items. |
| • | If the property is defined in the Property table, go to the Property Manager and delete it. |
| • | If the property is not on the SecureCustomProperties list, you can add this to the SecureCustomProperties property in the Property Manager. Multiple properties are delimited by semicolons. |
| • | Find the major upgrade item in the Upgrades view where the minimum version is higher than the maximum version and correct it. |
