ArcView Tip - Import71 utility does not complete
Problem: Certain ARC/INFO coverages cannot be imported into ArcView using the Import71 utility. There is not a size limit to an e00 file for the Import71 utility, but a newer version of a dll for the import71 utility fixes this problem.

Solution: This is a suggested workaround if your coverage does not complete with the Import71 utility provided in ArcView. There is a new Import71.exe on the www.esri.com site which contains a new dll than the one that exists in the exe in ArcView. Here is where one can find this new exe. http://www.esri.com/software/arcexplorer/aedownload.html
