There is an earlier version bug found on the microsoft website for this. Error 1935 is: An error occurred during the installation of assembly '[6]'. Please refer to Help and Support for more information. HRESULT: [3]. {{assembly interface: [4], function: [5], component: [2]}}
On older version this meant: This behavior occurs because Mscoree.dll is held in use for 10 minutes after you install (or remove) the assemblies. When you start another install, the installer tries to load its own version of Mscoree.dll to install the assemblies for the new program. Because another version of Mscoree.dll is already loaded, the failure occurs.
You can use either of the following methods to resolve this problem:
* Restart your computer.
-or-
* Stop Windows Installer (msiservice).
After looking through some forums I have also found another possible solution. Just before you install the programme try disabling your Anti-Virus software then install.
Remember to re-activate straight after attempting the install.
