Problem:
MicroStation crashes, for example, when loading a DGN when MicroStation is configured to automatically load the TSCAN application.
Probable Resolution 1:
Ensure that MicroStation and TerraScan were installed using the ‘Run as Administrator’ option by re-installing them ensuring to right-click on the setup.exe and select “Run as Administrator”.
Probable Resolution 2:
Delete the TerraScan User Preference File, TScan.upf, located in “Terra\TScan\”
