Memory usage was a primary consideration in developing this product. PUP 2000 is modular, so only the utilities that you actually use are loaded into memory. Plus, you can unload any or all of the utilities at any time to free up memory. I have an idea for a new utility for the next version of Power Utility Pak. The main requirement is that the utility must be general purpose in nature, and add something that's useful to a fair number of users.
Technical support is available by e-mail, directly from the developer.
Questions are typically answered within 24 hours, usually more quickly. First, check the PUP 2000 Update Site . An updated version of the utility may be available, and you can download the new file. The problem will be corrected, and the updated file will be made available to everyone. I developed an application that uses one of the custom worksheet functions contained in PUP 2000.
