If certain text and warning messages appear in German language despite the fact that you have set Datagraph-med to English (or any other of the available languages) it may be due to a German version of the Access Runtime. In that case you may want to install a local language version of Access Runtime.
For Office 2010 installations local language versions of MS Access Runtime are available here:
IMPORTANT: if updates for Microsoft Office become available please install them as datagraph-med usually is based on the latest available service packs.
You will have to de-install any preexisting Access Runtime versions before installing a new one.
Our Installation media and website download includes the 32 Bit version of Access Runtime. The 64 Bit version of MS Office is not supported.
