Opening AutoCAD .dwg Files Into a Single Instance of Solid Edge

I keep seeing this question come up, “Associating .dwg files with Solid Edge launches multiple instances of Solid Edge.  Is there a way to open the .dwg files into a single instance of Solid Edge?”

As it turns out there is.  GTAC Solutions Center article # 002-7002894 covers this very question.  You will need a WebKey account to access this article.

This is a Windows Explorer issue not a Solid Edge issue per se.  By tweaking the Windows Explorer registry we can make the .dwg files open into a single instance of Solid Edge.  Add or modify the following registry entries:

[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):

If you are not comfortable working in the registry then download this registry file and simply double-click to add the entries automatically.

Anybody have other Solid Edge registry tweaks they care to share?
