Abstract

A virtual installation map, and method involving installing a software functionality using the same, the virtual installation map including a first software installation map including a plurality of software elements representative of a related software file, the software elements also including at least one dependency to another software element. The virtual installation map further including a second software installation map also including a second plurality of software elements representative of related software file along with related dependencies. The first and second software installation maps may be hosted in separate databases and may relate to software products provided by different vendors. One or both software installation maps may include a pointer or other reference to the other installation map thereby providing a virtual installation map, in one example.

Claims

1. A method for validating and repairing a software installation comprising:

installing a first software file on a client computing device wherein the first software file is a subset of an installation of a first software functionality, the first software file further having at least one dependent software file presumed to reside on the client device;

determining whether the at least one dependent software file resides on the client computing device, wherein if the at least one dependent software file does not reside on the client computing device perform the operations of;

pausing the installation of the first software functionality;

removing the first software file from the client computing device;

requesting the at least one dependent software file from a software installation map, the software installation map comprising a plurality of software elements representing a plurality of software files including a first software element representing the first software file and the at least one dependent software file associated with the first software functionality, a plurality of dependency pointers representing a plurality of dependencies between the plurality of software files and a confidence factor associated with the plurality of dependency pointers indicating at least a number of a plurality of successful prior installations involving the plurality of dependency pointers;

receiving the at least one dependent software file from the software installation map;

installing the first software file and the at least one dependent software file on the client computing device; and

resuming the installation of the first software functionality.

2. The method of claim 1 further comprising:

applying a time stamp to the first software element signifying that the at least one dependent software file resides on the client computing device.

3. The method of claim 1 wherein each software element includes a uniform resource location (“

URL”

) reference to a memory location of the at least one dependent software file.

4. The method of claim 3 further comprising:

by way of a uniform resource locator for the at least one dependent software file, obtaining the at least one dependent software file.

5. The method of claim 3 further comprising providing for configuration of the software agent by a system administrator.

6. The method of claim 1 wherein the installing a first software file on a client is performed by a software agent residing on the client computing device.

7. The method of claim 1 wherein the determining whether the at least one dependent software file resides on the client computing device is performed by a validation thread of a software agent residing on the client computing device.

8. An apparatus for validating and repairing a software installation comprising:

a software agent residing on a client device, the software agent executed by a processing device of the client device and in communication with a software installation map residing on a server device, the software agent configured to;

install a first software file on the client device received from the software installation map, the first software file is a subset of an installation of a first software functionality, the first software file further having at least one dependent software file presumed to reside on the client device;

determine whether the at least one dependent software file resides on the client device wherein, upon determination that the at least one software file does not reside on the client device, the software agent is further configured to;

pause the installation of the first software functionality;

remove the first software file from the client device;

request the at least one dependent software file from a software installation map, the software installation map comprising a plurality of software elements representing a plurality of software files including a first software element representing the first software file and the at least one dependent software associated with the first software functionality, a plurality of dependency pointers representing a plurality of dependencies between the plurality of software files and a confidence factor associated with the plurality of dependency pointers indicating at least a number of a plurality of successful prior installations involving the plurality of dependency pointers;

receive the at least one dependent software file from the software installation map;

install the first software file and the at least one dependent software file on the client device; and

resume the installation of the first software functionality.

9. The apparatus of claim 8 wherein the software agent further comprises:

a validation thread configured to determine whether the at least one dependent software file resides on the client device.

10. The apparatus of claim 9 wherein the software agent is configurable to alter the determination of whether the at least one dependent software file resides on the client device.

11. The apparatus of claim 10 wherein the software agent is configured to determine whether the at least one dependent software file resides on the client device by obtaining file level access permissions of the at least one dependent software file residing on the client device.

12. The apparatus of claim 11 wherein the software agent is configured to determine whether the at least one dependent software file resides on the client device by accessing at least one high level symbol table associated with the dependent software file.

13. The apparatus of claim 8 wherein the software agent is configured to provide an indication of the presence of the at least one dependent file to the software installation map so that the software installation map may apply a time stamp to the first software element signifying that the at least one dependent software file resides on the client device.
