We have just released a fix for licensing and activation issues with Expression Web 4. Symptoms of licensing and/or activation issues include:

  • Expression Web 4 reverts to trial mode.
  • You receive a message that states that the product key is invalid.
  • The product key is not accepted during the Expression Web 4 installation process.
  • You receive a message that states that Expression Web 4 was already activated with the product key.

If you are seeing symptoms such as this, the fix we have released should resolve your issue. You can find details and a download link here:


To download the fix, click the "View and request hotfix downloads" hyperlink at the beginning of the article.

Please note that this fix is only for Expression Web 4. If you are encountering a licensing or activation issue with another Expression Studio product, you will need to open a support case with Microsoft to get that issue resolved.

If you download the patch and you receive an error that Web_en.msi could not be located, please download the "FullFile" version of the fix and install it on top of your existing installation. This will upgrade your existing installation of Expression Web 4 to SP2a which includes the fix.
