installation problem - new set up

I just downloaded dynare 6.4 to a new computer, along side a new matlab versions (2025). I get an error like the following when the program works on my older computer. I tried going back to the older dynare version 4.6.1 but messages are similar. Any help appreciated:

That is a common issue if you try to run mod files stored on cloud drives, see e.g.

Error terminate called after throwing an instance of 'std::filesystem::__cxx11::filesystem_error'

Are you on Windows? Can you copy the file to a separate folder on your disk where you have full write permissions. That folder must not be a network or cloud drive and should have a short path length. If you do so, can you still reproduce the error?

Many thanks for the input. The problem was indeed an issue about cloud drive (OneDrive). It is fixed now.

Best,
