I have MSE installed on several platforms XP 32 bit Vista 32 bit no issues just seems windows 7 64 bit?? Any ideas or thoughtsThomas R Grassi Jr

I think this problem is caused by the Microsoft Visual C++ Redistributable Package version you are running. Try updateing it to see if that helps or if it's already updated you can try a previous version. Here is a link to I think the newest version and at the bottom of that page are links to other versions. http://www.microsoft.com/download/en/details.aspx?id=5555

Hi, Based on my research, please try the following troubleshooting steps: 1. Install the latest the version of Microsoft Visual C++ 2010 Redistributable Package for x64 based system. 2. Temporary disable Microsoft Security Essentials and rename MSESysprep.dll to MSESysprep.dll.old, run Microsoft Security Essentials again and see how it works. If issue persists, it is recommended to post a new thread in Microsoft Security Essentials Community or submit a support case via Microsoft Security Essentials Support. Hope this helps.
