Were you just upgraded to the latest
Why you are getting the errors? The most recent update to CRM 2011 (Rollup 12) supports additional browsers (Internet Explorer, Firefox, Chrome, Safari) by generating HTML 5 that supports W3C standards. This requires removing dependencies on HTML components (HTC) that are specific to Internet Explorer.
For all Microsoft Dynamics CRM Online organizations, the default value for HTC support is ‘off’. If you have an existing script that requires HTC support or if you install a new solution that depends on HTC support you must change this setting to ‘on’.
For all on-premise CRM deployments, the default value for HTC support is ‘on’. If you have no scripts that depend on HTC support, you can change this setting to ‘off’ and enjoy better performance when using Internet Explorer.
To enable ‘HTC support in CRM Forms’, follow the steps below:
1. Navigate to Settings > Administration > System Settings
2. After opening System Settings, click the Customization tab
3. Find the section called HTML component support
4. Select the option Include HTC support in Microsoft Dynamics CRM forms
5. Click OK
Give this a try! If you are still having issues or need help with your Microsoft Dynamics CRM,
