How to Install Systems Center Capacity Planner on Windows 7

Had an issue installing Systems Center Capacity Planner on Windows 7 today… it would not. It kept prompting me with a blank window with the options “yes” or “no”. The Setup MSI package is looking for MDAC. MDAC already is included with Windows 7 so there is no need to install. Basically you need to edit the MSI package (editing MSI packages is highly unrecommended and any application packager would have my butt for this). I recommend using a free tool called InstEd. Remove all references to MDAC. There are three references you have to delete noted in the screenshots below.

After you have removed the references to MDAC from the MSI you have to open a command prompt as an administrator account and execute the Setup.msi from there. If you are installing the Operations Manager capacity planner on top of this you may have to run the MSI from an administrator command prompt as well.
