Use applications in your computer without installation.

APPLICATION VIRTUALISATION SOFTWARE

It is able to execute applications without them being installed in the traditional sense by virtualizing resources such as environment variables, files and Windows Registry keys. The virtual environment presented to the client is a merged view of the underlying physical and virtual resources, thereby allowing the virtualization layer to fool the application into thinking that it is running as if it were fully installed.

Some application virtualisation softwares:

1. VMware thinapp

ThinApp does not have any pre-installed components and does not require the installation of device drivers allowing applications to run from USB keys or network shares without ever requiring Administrator rights. ThinApp converts standard application installers such as .msi files into self-contained EXE files which includes everything required to run. Unlike self-extracting ZIP files, ThinApp does not extract files to disk or require system registry changes in order to run applications. ThinApp supports all released Intel-based Windows systems from Windows NT, 2000, XP, Vista, Server 2008, Terminal Server 2000 & 2008 from both 32bit and 64 bit editions. ThinApp does not yet support Windows 7.

2.Microsoft Application Visualisation

Microsoft Application Virtualization (MS App-V) platform allows applications to be deployed in real-time to any client from a virtual application server. It removes the need for local installation of the applications. Instead, only the App-v client needs to be installed on the client machines. All application data is permanently stored on the virtual application server. Whichever software is needed is either streamed or locally cached from the application server on demand and run locally. The App-V stack sandboxes the execution environment so that the application does not make changes to the client itself (OS File System and/or Registry). App-V applications are also sandboxed from each other, so that different versions of the same application can be run under SoftGrid concurrently. This approach enables any application to be delivered without making any changes to its code.
