Cannot uninstall Telerik ORM

Hi,

I am getting an issue where I cannot upgrade or uninstall my currently installed version of Telerik OpenAccess. It appears that this issue is occurring because I am missing an assembly 'Telerik_Data_Access_Free_Edition_2014_3_1027.msi ' but I do not have a copy of this available.

Any help would be appreciated.

The complete error log is as follows

PS: I have tried uninstalling using Add/Remove Programs and the Telerik Control Panel

Thank you for your response. The second link in your post (https://support.microsoft.com/en-us/mats/program_install_and_uninstall/en?wa=wsignin1.0) resolved the problem.
