Error 2343 Specified path is empty can occur during the installation process.
This error can occur on a new installation of the software if the main installation has not been processed first. The main installation sets the program and data paths into the system registry. If this information does not exist then the update or content installers cannot function correctly.To resolve this ensure you follow the installation order provided by this document.
Please note that when installing the Service Pack update you must ensure that the correct path to your Hevacomp installation is specified. This is especially important if you are installing on a 32-bit machine where the default installation location is likely to be slightly different (usually C:\Program Files\Bentley\Hevacomp V8i\Hevacomp).The easiest way to check is to right-click on your Hevacomp shortcut and have a look at the target location, listed under properties.
