I mean the standard them of your platform, e.g. for Windows, you can select the predefined standard theme on Display Properties > Themes. Please let me know changing to standard theme can solve the problem or not, thanks!
Thanks for replying. Do you mean with standard theme on Windows Vista but still cannot run DBVA-EC? If you don’t mind, could you please capture a screenshot of the error message when start DBVA-EC? Thanks in advance!
