Error Messages

Q1. During the easyPDF SDK installation, I keep getting the following error message:
AddPrinterDriverEx:The specified module could not be found.(126)

4. Click on the "Environment Variables.." button
5. In the "System Variables" window (the one on the bottom), scroll down to locate "Path" variable. Select that variable and click on the "Edit" button
6. In the "Variable Value" field, check to see that the following is listed somewhere in that string of values:
   %SystemRoot%\System32\Wbem, for example: C:\WINNT\System32\Wbem
7. If it's not, then please add it to the end (Don't forget to add a semi-colon to separate each variable). For example:
