Ran in to this one recently. During a recent attempt to add additional CAL’s to one of my SBS 2003 boxes, the license wizard would just close, regardless of whether I was trying to add, backup, or transfer licenses. Here are the steps that I took to resolve the issue.
Make sure that the DLL is registered properly by running the following from the command line: regsvr32 “C:\Program Files\Windows for Small Business Server\Administration\wizchain.dll”. You should get a message stated the the DLL registered correctly. Try to use the license wizard again and proceed to step 2 if the issue persists.
Go to System Properties and then click on the Advanced tab. Next, click on Settings in the performance category. Now click on the Data Execution Prevention tab. Make sure that “Add License Wizard” is excluded from DEP. If the license wizard isn’t listed, you will have to add it manually. After this apply / save your changes and re-run the license wizard.
After performing the above steps I was able to successfully add and backup SBS CAL’s on my server. Another classic case of Windows protecting Windows from Windows… Umm, yea.
