When you create an installer with LabVIEW, LabWindows/CVI, or TestStand, you have the option of copying each product installer included in the deployment to your computer. Those files will remain on your system until you uninstall or upgrade the products. Please note that cached packages used by NI Package Manager won't be removed once you uninstall or upgrade a software product, take a look at the Additional Information section for details on how to delete these files.
The installers will be stored in a different location, depending on the operating system that you are using. Here are the file locations for Windows XP, Vista and 7:Windows XP<Documents and Settings>\All Users\Application Data\National Instruments\MDF\ProductCache Windows 7 or Later<ProgramData>\National Instruments\MDF\ProductCacheNote: You will be prompted for the disks the next time you build an installer. You can also select to copy the files to your computer at this time.
These files can be deleted manually or a batch script can be created to automate the process of deletion. To automate this process, refer to Automatically Delete Files on Windows.
