Inventor ETO Series 2013 installs the ETO Series Studio 2013 extension, which will load by default. You cannot run 2012 and 2013 versions of the extension simultaneously, but you can switch between the two versions using the commands Restore Visual Studio 2012 Extension and Restore Visual Studio 2013 Extension located in the Start menu under Autodesk>Autodesk Inventor ETO Components 2013 R1. The VBScript that these shortcuts call is described below.
During installation, ETO Series 2013 creates a backup copy of the 2012 extension (if present) in the 2013 installation directory. By default, that directory is C:\Program Files\Autodesk\Inventor ETO Components 2013\ETOSeriesStudio2012. To restore this copy of the 2012 extension, use the following VB script:
...\Inventor ETO Components 2013\bin\vsExtensionRestore.vbs
Running this script without arguments displays an error message with a description of the usage included here.
vsExtensionRestore.vbs /Restore:{2012|2013} /VS2010:{VS2010 Install Path} /ETO:{ETO Series Install Path}
/Restore is either 2012 or 2013 to indicate which version of the extension to restore.
/VS2010 is the install location of Microsoft Visual Studio 2010.
/ETO is the install location of ETO Series Studio 2013.
vsExtensionRestore.vbs /Restore:2012 /VS2010:"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\" /ETO:"C:\Program Files\Autodesk\Inventor ETO Components 2013\"
Running /Restore:2012 makes a backup of the 2013 extension in the following folder (by default) C:\Program Files\Autodesk\Inventor ETO Components 2013\ETOSeriesStudio2013
To switch back to the 2013 extension, simply run the script as specifed above, changing the /Restore option to :2013, like this:
vsExtensionRestore.vbs /VS2010:"c:\program files (x86)\Microsoft Visual Studio 10.0\common7\ide\" /ETO:"c:\program files\Autodesk\Inventor ETO Components 2013\" /Restore:2013
