Solid Edge Open AutoCAD .dwg files by default from Windows Explorer into single instance of Solid Edge

By default AutoCAD files (.dwg) are not associated to the Solid Edge application in Windows Explorer.  Using 'Set your default programs' in Windows to associate AutoCAD files with Edge.exe will result in launching multiple instances of Solid Edge instead of opening the AutoCAD files into a single, already running instance of Solid Edge.

Solution

To force Windows Explorer to open AutoCAD .dwg files from Windows Explorer into a single instance of Solid Edge, add the following registry keys: 
 
[-HKEY_CURRENT_USER\Software\Classes\.dwg] 
 
[-HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dwg] 
 
[HKEY_CURRENT_USER\Software\Classes\.dwg] 
@="SolidEdge.DraftDocument" 
 
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dwg] 
 
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dwg\OpenWithList] 
"a"="Edge.exe" 
"MRUList"="a" 
 
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.dwg\OpenWithProgids] 
"SolidEdge.DraftDocument"=hex(0):
