After downloading and attempting to install the French language pack for Exchange 2010 UM I was less than pleased to the receive an error:

It took me a few moments to digest what was occurring but after reading the error (always a good start) and looking through the Exchange setup logs ([ERROR] Could not find a part of the path ‘C:\Support\UM,Language,Packs\fr-FR’), it would appear that if the Language Pack is in a folder that contains spaces it will not install.

If you look at the error above you will note that the spaces in my folder name have been replaced by comma’s ‘,’.

Resolution

Remove the spaces in the folder containing the Language Pack
