Hello, we have FNL on supercomputer with OS: Cent OS 6.5 And possibulity to run Comsol on Windows. I have a comsol project with imported external *.c library (dll, so). I solved project on linux machine and then try to interact with solution via gui and code on Windows. For Linux I use .os library for Windows .dll

And only if I have a solution from Linux with used external *.so library I have next error: File not found. - File I found log with correspond to this error it looks like this:

Solution: Comsol search for external lib which have same name as during computation. Best way avoid this error it's use File Schemes and File Handling and same name such as user:///mylib.dll

Solution: Comsol search for external lib which have same name as during computation. Best way avoid this error it's use [File Schemes and File Handling ](https://doc.comsol.com/5.5/doc/com.comsol.help.comsol/application_builder_manual_method_editor.50.13.html) and same name such as ```user:///mylib.dll```
