Patch Creation Utility

I need a tool to create application-fix packages. To fix errors in applications I have to deploy fix packages which generally consist of changed files and registry changes. I want a tool which can create self extracting exe files without any external dependencies which have the modified files and registry changes in compressed form in it. The creation tool should be developed in vb6 with perhaps an "split" screen where I can drag & drop my files and registry scripts from an explorer like view into the fixpackage view. The fixpackage view should also be a treeview where I can define the folders to copy the files on the target system to. This folderview should support windowsfolders (e.g. %SYSTEMDRIVE%, %SYSTEMROOT%...) At package creation there should be a single exe file which contains the install program, the files and registry scripts in compressed form. The exe should not have any dependencies to other files (e.g. zip-dlls). This exe file should be developed in vc6 and support copying locked files ( PendingFileRename-Operations ). Also the exe should support parameters (e.g. to install the files without user interaction, or to suppress a reboot). The information about files and registry entries in the self-extracting exe should be in a ascii file within the compressed sfx file to have the possibility to add extra logic if needed... ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform all Windows platforms
