Synopsis
Error: Could not load SiAppDll dll files
Solution
"TracePro is able to accommodate space balls, a substitute for a mouse that is sometimes preferred by CAD users. The error message you are receiving is because the space ball option is enabled but the space ball drivers have not been installed. If you do not have a space ball, please select View / Options and uncheck the box for "Enable Spaceball". If you do have a space ball, you need to download and install the drivers from the manufacturer's website."
