When you try to export your model to Advance Steel and the software crashes, don’t panic.

First, make sure you have the latest updates and hotfixes installed. If the problem persists, then clear your Windows temporary directory. Close any software you currently have open and then open the Run window by hitting the Windows + R keys together. Then type in %TMP% and hit the OK Button

Delete all the files or most of them that you can delete.

If this does not fix the problem, then download the Microsoft Access Database Engine 2010 Redistributable

Choose the 64 bit version

After downloading, install the package.

First, try a repair or install if not yet installed.

After install try the export again. If the problem persists, then uninstall and reinstall the Microsoft Access Database Engine 2010 Redistributable
In my case, performing the above actions fixed the problem. I was able to successfully export the Revit model to the required .smlx file format. There is much to understand regarding the interaction of Revit and Advance Steel models. I am currently researching how they relate to each other and map their steel members. In future blogs, I will be relating my venture into the subject.

It is possible that it might not be the same in your case. Then you need to perform a clean uninstall of your Revit products, and worst-case scenario, a clean uninstall of all Autodesk Products.
