Strange one this… I recently released a new version of a product in ConfigMgr, configured supersedence and waited for the defined uninstall/update to occur – only it didn’t. The software appeared to download on the client as expected (both old and new version) and then without any update in AppEnforce.log the deployment failed with an 80091007 error code.
On further investigation CAS.log contained the following:

Content hash verification had failed.. strange as the MSI had been tested and was working. I simply updated the deployment content , waited for this to distribute and tested again without issue…!
