Error: Invalid product license when opening a web console

Problem:

Possible resolutions:

1. If the 32-bit Core Console cannot be loaded then contact licensing to correct the license file. After correcting the licensing information, reactivate the core server.
2. Check the c:\windows\Temp directory. If there are a lot of .tmp files then:
   1. Open services.msc and stop the IIS admin service and the dependent services
   2. Delete all the files in the temp directory
   3. Run iisreset

Note: Running a directory at the command prompt may be necessary to determine that this folder is empty. Several problems have happened when opening the folder in Windows Explorer and it contains 65,000+ files.

Note: Sometimes the temp directory is not at C:\Windows\Temp. This is dependent on the OS configuration. Alternative options include C:\WinNT\Temp. The best way to find the correct directory is to open a command prompt and run:

cd %windir%\temp

or select Start -> Run and run:

%windir%\temp

Please check with particular care for the presence of any additional Temp folders that you may have defined in your environment. Not erasing the correct temp folder will result in failure of the resolution of your issue.
