My appologies if this is posted in wrong category. Also, I am not an avid end-user of ArcGIS or PLTS, just an IT guy trying to resolve a problem. I have loaded ArcGIS 9.3.1 with PLTS on several machines. Everything works great, except one utility, the PLTS Geodatabase to Shape (PLTSGDB2Shape.exe). When this utility is invoked, the initial dialog pops up and user must hit the browse button to locate a geodatabse file. As soon as they click this browse button an error dialog pops up. Title says "Connect" and messaage says "Failed to connect to database. The Product License has not been initialized." This is only happening to just a few of my users, the others have no issues. I have a mixture of Windows7 and WindosXP machines and this is happening on both. To make things more interesting, I can completely uninstall ArGIS and PLTS, then re-install . . . the problem goes away. What resons(s) could cause this error?
