Hi Amy,
Autodesk Showcase Professional 2010 and 2011 use license management. For network licensing the 2010 version of Autodesk Showcase Professional uses the Alias vendor daemon (sgiawd.exe) for FLEXlm version 11.4. If you wish to use Autodesk Showcase Professional 2010 you will need to setup separate services for Autodesk and Alias products or combine the service into one. Autodesk Showcase Professional 2011 uses the Autodesk vendor daemon (adskflex.exe) for FLEXlm version 11.8. You may wish to upgrade to the 2011 version of your suite.
There are several ways that you can set up the license services. Some use separate computers or other configurations. My preference is to set up separate services and have separate debug log files. For only the Alias and Autodesk products it is fairly simple to install and configure them on the same computer as their documentation recommends. The Alias service and the Autodesk service will by default use different TCP/IP ports therefore reducing crosstalk and other problems often encountered with multiple services.
I like to make this even simpler. If you already have the Autodesk Network License Manager for 2010 (FLEXlm 11.4) or 2011 (FLEXlm 11.7) installed drop the sgiawd.exe (attached to this post, 11.4 version) file into the Autodesk Network License Manager folder, then configure another service with the lmgrd.exe from the Autodesk Network License Manager folder, your additional license file for Alias products, and a new debug log. The important thing is that you are using a vendor daemon version that supports the product you are using with a master daemon (the lmgrd.exe) that is the same version or newer.
What troubles are you having with your network license manager? I or many of the community members can assist you with that.
