Why does the Altera PLL fail to launch?

Description

Due to a problem in Quartus® II software version 14.1 and earlier, you may see the Altera PLL fails to launch. This problem occurs when you create/edit Altera PLL using Qsys, IP Catalog or the MegaWizard™ Plug-in Manager. The problem is caused by the tbbmalloc.dll in the c:\windows\system32 directory.

Resolution

To work around this problem, remove the tbbmalloc.dll from the c:\windows\system32 directory.

This problem is scheduled to be fixed in future release of the Quartus II software.
