If an application does not provide the Repair option in Programs and Features, it must be first uninstalled and then reinstalled to repair missing or corrupt application files. Windows compatibility Because some applications use elements that are specific to a certain version of an operating system, you may run into problems when trying to use these same programs on newer operating systems. Windows Compatibility Mode is designed to correct this problem by creating an environment that emulates the operating system for which the application was originally intended. In compatibility mode, you choose a target operating system (such as Windows Vista). When the application runs, it appears as if the application is running on the target operating system. To configure Compatibility Mode for an application, edit the properties of its shortcut or executable file. On the Compatibility tab, configure the following as appropriate: Operating system compatibility mode Reduced color mode

Run in 640x480 screen resolution Disable display scaling on high DPI settings Run the program as an administrator If you're not sure which settings to use, you can run the Compatibility Troubleshooter from the Compatibility tab. This utility will probe the application and automatically determine the correct compatibility settings. Windows 7 Enterprise and Ultimate editions also provide Windows XP Mode . This feature is not included with the operating system and must be downloaded separately. Windows XP Mode provides a Windows Virtual PC containing a pre-installed copy of Windows XP Professional. You can use this virtual machine to run older applications that don't run correctly on Windows 7. The applications running within the virtual environment are accessed using the Remote Desktop Protocol and thus appear to be running on the Windows 7 host operating system itself. Permissions On older versions of Windows, applications ran with the privileges associated with the user who ran the application. But on modern versions of Windows, applications run by default as a standard user, even if the user who launches the application is an administrator. This is done to contain damage that could potentially result if the end user launches a poorly-written or malicious application. However, some applications need to run with administrative privileges to be able to complete necessary tasks. Be aware of the following permission-related issues when running applications: Using UAC in modern versions of Windows, applications run with standard user privileges by default. The user will be prompted if the application requires elevated permissions. Older applications written for previous versions of Windows may not be compatible with UAC. They may assume that they can run with administrator-level privileges.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
