You are unable to deploy software and you get the message - Failed with an unknown error, during the process.
You will encounter this as a result of some specific error related to the application being installed. The reason may be as follows:
To eliminate Software Deployment failure with Unknown Error Code error message, try the following options:
Remove files of earlier installations before Reinstallation
Software that were not removed completely from Add/Remove programs, can create problems when you try to do software deployment. Use Microsoft’s Windows Installer Cleanup utility to remove traces of previous installations. This utility does not remove files installed by the installation, which may need to be removed manually. For more information, refer to Microsoft’s knowledge base article Description of the Windows Installer CleanUp Utility. Once removed, try reinstalling the software.
Ensure the User account has administrative privileges to install software
If UAC has been enabled in the system and you wanted to install the software using system account or administrator account, you will get the "unknown error code". Ensure that you have enough privilege to install the software. Follow these steps to confirm administrative rights on your computer:
Ensure there are no problems with silent switches
Try installing the application manually in one computer using the silent switches. In case you get pop-ups, then check from the vendor, whether the switches are valid. Else inform the user in prior to accept any pop-up that may appear.
Ensure there is enough disk space for file extraction
Most software get extracted in the drive where the OS is installed and are then copied to the destination directory. So even if the destination drive has enough space, you are likely to get this error. Clear some files from the OS installed drive and try deploying the software.
