Advance Steel Crashing after installing the Powerpack for Advance Steel

We have been getting a lot of support cases where Advance Steel is crashing on startup after installing the Powerpack for Advance Steel. When the user launches Advance Steel, it crashes immediately with the following error messages:

3   4

The cause of this issue is either the user Everyone is missing from the Security tab for AS files and folders, or there are LDF files that do not match MDF files.

Please delete all .ldf files found under C:\ProgramData\Autodesk\Advance Steel 2019\USA (similar location for different year versions). When you are at the USA folder, you can do a search for .ldf in your Windows Explorer and it will pull all .ldf files in that file path:



Next, check the USA folder properties (select USA folder >> right click and select Properties). Under the Security tab, see if the user Everyone is in the list. If not, add Everyone to the list with full access permissions:
