# I have a .NET desktop app that needs 2 pre-requests to run. Please create an installer that can carry out download and installation of the pre-requests and our program. Thus the users will experience very simple installation. # In other words, the installer will be similar to Microsoft Web Platform Installer, only much simpler. ## Deliverables **More background:** -- The two pre-requests are from Microsoft, they are .NET Framework 4.0 and specific version of SlimDX. -- Our desktop app has .NET setup (MSI) files for both 32-bit and 64-bit PCs. **Requirements of the project include:** * The installer will -- Check if .NET 4.0 is installed at the targeted PC; if not, will invite the user to land on Microsoft .NET 4.0 download site -- Check if other versions of SlimDX other than the specific version are installed at the targeted PC; if yes, will ask the user to uninstall them -- Check if the specific version of SlimDX is installed; if not, will invite the user to download and install from our website; the version/file name should be easily configurable since our app may target different versions of SlimDX in the future -- Check if the targeted PC is 32bit or 64bit, and download the appropriate version of setup files from our website accordingly; again the version/file name should be easily configurable since we will keep on releasing new files in the future; * The installer must visually look appealing; * The installer itself must be portable across both 32bit and 64bit PCs on at least Windows 7 and Vista; * You can use third-party solutions for this project, but the whole deliverable must be easy and cheap to maintain and upgrade. **Resources to be provided:** -- The URL for the specific version of SlimDX -- The URL for different versions of our setup files. **Deliverables:** -- Install program/code/script that meets the above requirements. -- Any other necessary documentation, e.g. third-party references if any **To Bid** Preferably you have done similar projects.
