These changes can include writing files to the **C:\\Program Files** directory, making registry changes, starting and stopping services, updating security descriptors for files, and changing permissions. Before you install the Sequencer and after you sequence each application, you must restore a clean operating system image to the sequencing computer. You can use one of the following methods to restore the computer running the Sequencer: - Reformat the hard drive and reinstall the operating system. - Restore the hard drive on the computer running the Sequencer image by using another disk-imaging software. - Revert a virtual operating system image such as a Microsoft Virtual PC image. Using a virtual machine allows for clean sequencing environments to be easily reused with minimal administration. The following list outlines the recommended hardware requirements for running the App-V Sequencer. The requirements are listed first for Microsoft Application Virtualization (App-V) 4.6 SP2, followed by the requirements for versions that preceded App-V 4.6 SP2. ### Hardware Requirements - Processor—Intel Pentium III, 1 GHz (32-bit or 64-bit). The sequencing process is a single-threaded process and does not take advantage of dual processors. - Memory—1 GB or above, 2 GB recommended. - Hard disk—40 gigabyte (GB) hard disk space with a minimum of 15 GB available hard disk space. We recommend that you have at least three times the hard disk space that the application you are sequencing requires. **Note** Sequencing requires heavy disk usage. A fast disk speed can decrease the sequencing time. ### Software Requirements for App-V 4.6 SP2 The following list outlines the supported operating systems for running the App-V 4.6 SP2 Sequencer.

Operating System	Edition	Service Pack	System Architecture
Windows XP	Professional	SP3	x86
Windows Vista	Business, Enterprise, or Ultimate	SP2	x86
Windows 7	Professional, Enterprise, or Ultimate	No service pack or SP1	x86 and x64
Windows 8	Professional or Enterprise Edition		x86 and x64

**Note** The Application Virtualization (App-V) 4.6 SP2 Sequencer supports 32-bit and 64-bit versions of these operating systems. You should configure computers running the Sequencer with the same applications that are installed on targeted computers. ### Software Requirements for Versions that Precede App-V 4.6 SP2 The following list outlines the supported operating systems for running the Sequencer for versions that precede App-V 4.6 SP2.

Operating System	Edition	Service Pack	System Architecture
Windows XP	Professional	SP2 or SP3	x86
Windows Vista	Business, Enterprise, or Ultimate	No service pack, SP1, or SP2	x86
Windows 7¹	Professional, Enterprise, or Ultimate		x86

¹Supported for App-V 4.5 with SP1 or SP2, and App-V 4.6 only **Note** The Application Virtualization (App-V) 4.6 Sequencer supports 32-bit and 64-bit versions of these operating systems. You should configure computers running the Sequencer with the same applications that are installed on targeted computers. ### Software Requirements for Remote Desktop Services for App-V 4.6 SP2

Operating System	Edition	Service Pack	System Architecture
Windows Server 2003 R2	Standard Edition, Enterprise Edition, or Datacenter Edition	SP2	x86
Windows Server 2008	Standard, Enterprise, or Datacenter Edition	SP2	x86
Windows Server 2008 R2	Standard, Enterprise, or Datacenter Edition	No service pack or SP1	x64
Windows Server 2012	Standard, Enterprise, or Datacenter Edition		x86 or x64

**Note** Application Virtualization (App-V) 4.6 SP2 for Remote Desktop Services supports 32-bit and 64-bit versions of these operating systems. ### Software Requirements for Remote Desktop Services for Versions that Precede App-V 4.6 SP2

Operating System	Edition	Service Pack	System Architecture
Windows Server 2003	Standard Edition, Enterprise Edition, or Datacenter Edition	SP1 or SP2	x86
Windows Server 2003 R2	Standard Edition, Enterprise Edition, or Datacenter Edition	No service pack or SP2	x86
Windows Server 2008	Standard, Enterprise, or Datacenter Edition	SP1 or SP2	x86
Windows Server 2008 R2	Standard, Enterprise, or Datacenter Edition	No service pack or SP1	x64

**Note** Application Virtualization (App-V) 4.6 SP2 for Remote Desktop Services supports 32-bit and 64-bit versions of these operating systems. ## Related topics [Application Virtualization Client Hardware and Software Requirements](application-virtualization-client-hardware-and-software-requirements.md) [Application Virtualization System Requirements](application-virtualization-system-requirements.md) [How to Install the Application Virtualization Sequencer](how-to-install-the-application-virtualization-sequencer.md) [How to Upgrade the Application Virtualization Sequencer](how-to-upgrade-the-application-virtualization-sequencer.md)
