FAQs
Learn about Frequently Asked Questions (FAQs) when updating HP Capture and Route (HP CR) for the Microsoft DCOM patch.
I don’t use remote components in HPCR. It’s all on one server. Am I still affected?
Yes. HPCR uses DCOM to process data between its individual components, services, and DCOM-based applications (including HPCR Client software).
By what date do I need to apply the update or upgrade to assure there will be no interruption?
We suggest either implementing the documented change to keep the current defaults for DCOM published and provided by Microsoft or applying the patch as soon as it is available. Updates should be made no later than June 13, 2022.
I’m on HPCR 1.5. Am I still affected?
Yes. All versions of HP CR will be affected. Patches for versions 1.8, 1.9, and 2.9 were released on June 2, 2022.
I’m on Windows Server 2012 R2. Am I still affected?
Yes. It does not matter which server operating system you are running on. These changes will be included in all supported Microsoft operating systems for update.
