RenewCert - Renew Expired Certificates

It's been just over a year when I deployed the RuleManager with a ClickOnce certificate. Today it expired. Visual Studio 2005 would suggest to generate a new certificate file, however none of the existing users would be able to update the Application (because of different certificate keys).
The error you would get is:

System.NullReferenceException: Object reference not set to an instance of an object.
at System.Deployment.Application.ApplicationTrust.RequestTrust(SubscriptionState subState, Boolean isShellVisible, Boolean isUpdate, ActivationContext actCtx, TrustManagerContext tmc)
at System.Deployment.Application.DeploymentManager.DetermineTrustCore(Boolean blocking, TrustParams tp)
at System.Deployment.Application.DeploymentManager.DetermineTrust(TrustParams trustParams)
at System.Deployment.Application.ApplicationDeployment.CheckForDetailedUpdate()



There is a workaround made by Cliff Stanford RenewCert, which allows you to regenerate an expired certification.

Thanks Cliff!

Graphical Rule Editor for RuleML format


In the last few weeks we have created the RuleML adapter for the Rule Manager. The RuleML adapter allows to export a business rules policy to the Reaction RuleML format.

Please bear with us that we are no experts in RuleML and certain rule constructions might be exported incorrectly. I hope the RuleML community can provide us with the feedback and we will incorporate any changes into our automatic update process as soon as possible. You can give feedback at the http://www.acumenbusiness.com/support forum.

Installation:
The Rule Manager product is available from the website http://www.acumenbusiness.com/

You can export to the RuleML format by installing the RuleML adapter module. See the screenshot [Menu: File\Options\Adapters\Rule ML]

The adapter will provide the new export format "RuleML (*.rrml)" in the Export wizard. [Menu: File\Export]
You can set .rrml as the default export type by changing the File Export type on the Import & Export options
[Menu: File\Options\Import & Export\File Export = RuleML (*.rrml)]

An example of the Driver Eligibility export is here
