4: Verifying that type .SVG MIME is present
System Architect XT uses the .SVG file format to display diagrams and charts. If diagrams do not display correctly, check that the SVG setting in IIS is setup properly.
1 Click on the Mime Types icon.
2 Look to see if extension column already contains the value .svg image/svg+xml.
3 If .SVG is not displayed in the list, click Add.
4 Enter .svg in the File name extension field, and enter image/svg+xml in the MIME type field, and click OK.
