When trying to open a model from an old version of StormCAD, such as StormCAD version 5.6, the following error message is generated: "Database format not recognized or read-only. It could not be opened."
This issue can be easily resolved by open the 32-bit version of StormCAD. You can find this by going to "C:\Program Files (x86)\Bentley\StormCAD8" and double-clicking on the StormCAD.exe file. This will open the 32-bit version of StormCAD.
Once this is open, go to File > Open and select the .STM file. The model file should open without issue. Once the model file is saved in the current format, you will be able to use either the 32-bit or the 64-bit version of StormCAD without any problem.
