I currently have multiple versions of AutoCAD installed on my machine (AutoCAD 2004, AutoCAD Electrical 2007, AutoCAD Electrical 2008, and AutoCAD 2010). After installing 2010 an issue began that I had solved with past releases however it has stumped me this time.
Typically I open all drawing files via Windows Explorer as opposed to doing so from within AutoCAD using the "Open" command. After installing 2010 when I double click a file it opens in 2010 however I need for it to open using 2008.
From within Windows Explorer I went to "Tools...Folder Options...File Types". I then selected the "DWG" file type and hit browse. I then selected the acad.exe executable which is located within the AutoCAD 2008 folder. Now when I double click a file it opens it using AutoCAD 2004.
I believe part of the issue is a result of all AutoCAD executables being named "acad.exe" as opposed to "acad2008.exe, etc". Is anyone aware of a system variable or any other method that would control which version is used to open drawings?
Any assistance is greatly appreciated.
