A computer with Microsoft .NET Framework installed may show error 1935. This
generally occurs while the MSI files are trying to install various policy
files
on your computer during the setup operations.

Following are the various ways you can implement to fix error 1935

1. Reinstall Microsoft .NET Framework
2. Perform a Full Virus Scan
3. Full Scan your Registry
4. Re-register Windows Installer
5. Check System Files for Corruption
6. Clean the System Junk
Try this i am sure your problem solution is here,
