How To Repair The 1335 “Office1 Cab” Error On Your PC

  • Check for installation CD damage

    The installation CD can be damaged or may have scratches on it. This restricts the drive to read the CD. If you are trying to install something on your computer using a CD, you should first check whether the CD is damaged. If it is damaged or scratched in any way, your computer may not be able to read the files on the CD. If it is scratched, you should look for a replacement CD or use one of the CD repair tools that you can get from PC stores

  • Extract the compressed installation files

    Error 1335 indicates that you cannot extract a “CAB” file from an installation program. The installers use a CAB (.cab) file to compress a large number of files into a single smaller file. If you are seeing this error 1335, it means that either the .cab file is damaged, corrupt or is not readable. The simplest way to solve this is to manually extract the file. To extract the file, do the following:

    1- Right-click the folder and select Extract All.
    2- Follow the instructions.
    3- Once done, double-click “Setup.exe” in the folder containing the extracted files.

  • Clean the registry

    The “registry” is a central database that stores parameters and information vital to your system. It is also, above all, where Windows stores many vital parameters for the heart of your system. One of the biggest problems causing error 1335 is the number of damaged registry files that cause errors on your computer. To resolve this issue, it is highly recommended that you use a “registry cleaner” to scan your computer and repair various corrupt registry settings that could be causing a problem within your system.

Use the above steps to fix the Microsoft Office 1335 error and continue using the applications without any problem.
