J.C put this post up today and it was certainly an important update for me. I went straight to the site and downloaded it, and installed the update to my vista client. Highly recommenced this update!
Just a quick heads up that there are new builds of the SoftGrid 4.2 clients available for download. The new build number is 188.8.131.520 and the SoftGrid 4.2 KB article (http://support.microsoft.com/kb/941408) has been updated to point to the proper download locations. Note that applies to the SoftGrid for Windows Desktops clients only.
These new client builds contain a fix for an issue where under rare circumstances, performing a Package Upgrade may result in an incomplete update leading to possible package corruption. We recommend upgrading to the new client to prevent these problems going forward. We will be posting future SoftGrid updates to the KB article above and on this blog so be sure to check back every so often for the latest news.
