Abstract

Claims (30)

1. A method for virtualizing software applications, the method comprising:

initializing a virtual environment created by a virtual engine executed over a computer;

launching an installation process of a software application to be virtualized, wherein the installation process runs in the virtual environment; and

capturing all data writes performed during the installation process and saving the captured data writes to a new data file,

wherein the new data file, upon completion of the installation process, does not store an operating system.

2. The method of claim 1 , further comprising:

upon completion of the installation process disabling write permissions to the new data file; and

saving the new data file as an application-on-demand (AOD) file.

3. The method of claim 2 , wherein the AOD file includes all the information required to execute a virtual software application that corresponds to the software application.

4. The method of claim 3 , wherein the AOD file comprises at least an internal virtual services manager, a digital rights management layer, a connectivity layer, and a protection layer.

5. The method of claim 1 , automatically launched when a user attempts to install the software application in the virtual environment.

6. The method of claim 1 , wherein the computer is not a clean machine.

7. The method of claim 1 , wherein the data writes to the file system include at least one registry key.

8. The method of claim 1 , wherein the virtual engine is an executable computing environment.

9. A non-transitory computer readable medium having stored thereon computer executable code when executed causing a processor to perform the process of virtualizing software applications, the process comprising:

initializing a virtual environment created by a virtual engine executed over a computer;

launching an installation process of a software application to be virtualized, wherein the installation process runs in the virtual environment; and

capturing all data writes performed during the installation process and saving the captured data writes to a new data file,

wherein the new data file, upon completion of the installation process, does not store an operating system.

10. The method of claim 1 , wherein the data writes to the file system include at least one dynamic link library (DLL) file.

11. The method of claim 1 , wherein the data writes to the file system include at least one named object.

12. The method of claim 1 , wherein the virtual engine includes a file system, a registry repository, a dynamic link library (DLL) repository, and named objects.

13. The non-transitory computer readable medium of claim 9 , the process further comprising:

upon completion of the installation process disabling write permissions to the new data file; and

saving the new data file as an application-on-demand (AOD) file.

14. The non-transitory computer readable medium of claim 13 , wherein the AOD file includes all the information required to execute a virtual software application that corresponds to the software application.

15. The non-transitory computer readable medium of claim 13 , wherein the AOD file comprises at least an internal virtual services manager, a digital rights management layer, a connectivity layer, and a protection layer.

16. The non-transitory computer readable medium of claim 9 , wherein the data writes to the file system include at least one dynamic link library (DLL) file.

17. The non-transitory computer readable medium of claim 9 , wherein the virtual engine is an executable computing environment.

18. The non-transitory computer readable medium of claim 9 , wherein the virtual engine includes a file system, a registry repository, a dynamic link library (DLL) repository, and named objects.
