Critical Issue
Description
The Run as ModelSim command might fail on launch configurations created in version 7.0 or earlier of the IDE. This problem does not occur for new launch configurations.
Resolution
Select a location for the ModelSim tool from the launch configuration dialog box. You can use the Browse button next to the ModelSim path group, or type in a path to the ModelSim directory (for example c:/altera/71/modelsim_ae/win32aloem).
