When installing MS OFFICE it runs to approximately 80% then fails with an Error 1935 and begins a rollback of install.
1. Confirm no prior versions of MS Office are installed. It is suggested that you run the Office Uninstall Tool
( This tool may need to be run multiple times until it is confirmed the computer does not have a version of Office installed )
2. Download and run the .NET Framework repair tool
4. Try the install of OFFICE again.
