Have any of you experiencing this before an idea of what the error is meant ?

I have tried uninstalling webmatrix2 then reinstalling it but everything fails the same way. Thank you.

Had the same problem but solved it by manually uninstalling IIS Express 7.5 and WebMatrix. Then I downloaded IIS 7.5, MSSQL Server Management Objects, and WebMatrix then installed it manually. My PC shutdown while installing through WebPI which may have caused the issue for me.

The links below are the ones I copied from WebPI:

IIS Express 7.5: http://download.microsoft.com/download/D/C/4/DC4EC38C-A6AA-449D-9B19-7ABC6DF72B34/iisexpress_1_11_x86_en-US.msi

MSSQL Server Management Objects: http://download.microsoft.com/download/F/E/D/FEDB200F-DE2A-46D8-B661-D019DFE9D470/ENU/x86/SharedManagementObjects.msi

WebMatrix 2: http://download.microsoft.com/download/8/5/7/8573745C-384B-4F74-BE2C-D85C390742D5/WebMatrix_x86_en-US.msi

Hope this helps.
