I'd like to give an update on the Microsoft Dynamics CRM 2011 Update Rollup (UR) 12 Release. We originally made UR12 available on Thursday, January 10th, to deliver multi-browser support for our On Premises customers. After discovering an issue that could potentially impact a customer's database, we withdrew the UR12 Server bits to ensure that no On Premises customers would be affected. Unfortunately, these bits were available on the Microsoft Download Center for a short period of time. If you downloaded the UR12 Server bits, please do not install them. We plan to repost the UR12 Server bits within the next week, and we will keep you informed as to when they are available. We have taken measures to improve our engineering processes and methodologies going forward, and we take your feedback very seriously. We apologize for any inconvenience this has caused.
Corporate Vice President, Microsoft Dynamics CRM
