The language of this installation package is not supported by your system.

Yesterday I downloaded the Office 2010 trail and tried to install. Previously I have used the Beta1 also in its early days. After re-installing the Window I stick to the Office 2007 because I was facing some issues in the beta so I prefer to wait for the stable version.

The direct installation attempt was not successful because even after uninstalling the Office 2007 there were still some components (like office connector for WLM 2011) that were required to be removed. To avoid the delay in extraction each time then getting the error of still some components remaining for uninstall, I extracted the exe file (ProfessionalPlus.exe) with WinZip. After  fully remove the required components, I executed the installer from the extracted files and I got a new error:

office language error: The language of this installation package is not supported by your system.
The language of this installation package is not supported by your system.

It was really strange for me because I clearly remember selecting the language as English. I cross checked the language of my system but I could not find the gap.

After googling the issue I came to know that the cause of this error is the extraction method. Why it is so, it does not make any logic.

The contents generated by WinZip (or other similar extraction tools) look like this:

Extracted contents using WinZip

Solution

The correct way is the use the extract command line switch to extract the setup:

Extract Command to extract office setup

Open the command prompt and navigate to the folder containing the setup file (in this case its D:\OfficeSetup) and execute the following command:

ProfessionalPlus.exe /extract:[Destination]

In this case the [Destination] is D:\Office2010

When the setup is extracted this way, we get the proper progress for the extraction followed by the confirmation:

Microsoft Office Professional Plus 2010 extraction

The output generated in this way looks like this:

Office_2010_extracted_using_commandline_switch

Bonus Tip:

In case if you do not know, to open the command prompt directly to any folder in the explorer use this shortcut:

Shift + Right Click on Folder Name

Open Command Window Here Context Menu
