Why won't my DWG prompt for check out (mime type issue)

  • PDF

Article summary

Scenario: When opening a DWG from within 12d Synergy for editing, users usually get prompted for them to checkout the dwg.

In this case, 12d Synergy does not prompt the user to check it out before editing.

Cause: Third party applications(usually image viewing software), upon installation, sometimes changes how Windows understands the file type dwg, which often leads 12d Synergy to think it is an image format.

Solution: Set the Content Type of DWG files to application/dwg

Steps

In Windows Start > Run > regedit,  or Windows Key + R then type regedit

*You may need to run regedit as an administrator to be able to make changes in the registry.

On the Address bar, below the menu bar, paste this value Computer\HKEY_CLASSES_ROOT\.dwg, and press Enter.


Right Click on Content Type, then click Modify

Change the value data from image/vnd.dwg to application/dwg, and then click OK
