Thank you for trying CacheMaster. Required Files: If you find that you cannot open the CacheMaster.msi file, then you need to install the latest Microsoft installer files. It is also necessary that the Visual Basic 6 runtime files are installed prior to installing this software. Both of these can be found at my website: http://www.codearchive.com/~mark/index.html I left these files out to keep the download size to a minimum for those who already have them. Important Note: If your computer uses an AGP graphics card, then it is important that you do not set your minimum cache size to less than the size of your AGP aperture. This is usually 64Mb, but the exact setting can be found in your computers bios setup. Setting the maximum cache size to less than the aperture size can cause poor video performance or even system lockups. This program is freeware, and can be distributed freely. If you have any problems, questions, or if you just want to chat, feel free to contact me at balthazor@prodigy.net Thanks again, and have a great day! Mark Balthazor
