There could be two reasons for getting these errors when starting Molecular Conceptor:
1. The user tried to run Molecular Conceptor (Demo or Evaluation version) from the internet, without first saving the file to a local file.
Solution: Save the 'mc2_demo.exe'\'mc2_eval.exe' file to your local machine and activate it from there. There is a security policy that restricts the permissions to run non-local code.
2. (Windows 2003) The user tried to run Molecular Conceptor from a mapped drive.
Solution 1: Use a local copy of Molecular Conceptor files.
Solution 2: Use Molecular Conceptor from another share name.
A name without special signs that may cause the problem. (e.g.: '$', '@', ...)
