Are you exporting the profile directly (from right-click or toolspace)? Have you tried exporting the all data from the File menu and then using the LandXML reporting (it'll just pick up what you NEED for each particular report)?
Let's be clear; this is NOT an export operation
It's a Toolbox>>Reports Manager>>Profile Reports....most of which are XSL, or now .NET report forms....
The user should be able to rtclick on the report....and then either let the application select ALL profiles (default) or select the object from screen (option button in lower left quadrant)
Then they click OK, and moments later a browser window opens, along with a prompt about allowing Active X content to run...the user clicks OK the report appears...before that it will look like empty browser window...
I suspect they are perhaps NOT using explorer as default browser....
