I’ve been using Windows 7 for a while now, but I’ve never needed to install the System Center Capacity Planner (Andy usually handles that side of our SharePoint engagements). He now has taken the plunge with Microsoft’s shiny OS and hit a problem: SCCP refused to install with an error message saying it was only supported on Windows XP (!)
We tried all sorts, and in the end I resorted to our old friend, Orca – the MSI editor shipped with the Windows SDK. Looking through the tables I found an entry in LaunchCondition specifying ‘VersionNT >=500 AND VersionNT <=600’
One quick hack later and it was looking for less than ‘700’ and the installer worked.
Luckily, the SharePoint Planning installer needed no such hacking.
