System Center Configuration Manager (SCCM) 2007 Installation Troubles I recently came across some issues installing System Center Configuration Manager (SCCM) 2007 in a disconnected/lab environment. During the installation, you are prompted to download updated prerequisite files, or give SCCM a path to where you've already downloaded them. Setup will not let you proceed without properly performing this step. After doing some additional searching, I finally came across a post by Jeff Gilbert, which stated, "To download the files from a different computer, just start Configuration Manager Setup on a computer with Internet connectivity and use the following command: Setup /download ."

Here is a link to the original post:

I hope this helps someone else, who comes across a similar error. The error message itself says "Component manifest was not found or it is invalid." I tried simply creating the file it was looking for, called ConfigMgr.Manifest.cab, but then the ConfigMgrSetup.log file indicated that it failed to validate the digital signature, so it looks like there's no getting around it without doing it properly.

Oh well .... on with the installation ....  ¶ 3:36 PM 0 comments
