Failed to launch MegaWizard™ Plug-In Manager. PLL Intel® FPGA IP v18.0 could not be found in the specified library paths - Failed to launch MegaWizard™ Plug-In Manager. PLL Intel® FPGA IP v18.0 could not be found in the specified library paths Description In the Quartus® Prime software version 18.0, when you want to open the MegaWizard™ for editing, you may see error message "Failed to launch MegaWizard™ Plug-In Manager. PLL Intel® FPGA IP v18.0 could not be found in the specified library paths". Resolution To work around this problem, 1) Locate the .lst file of the missing IP in your Intel® FPGA program directory. For example, for the missing PLL, locate "pll_wizard.lst". In the case of Windows: Windows <installation_directory> \ip\altera\altera_pll In the case of Linux: Linux <installation_directory>/linux64/ip/altera/altera_pll 2) Change the text. "<ALIAS>Altera® PLL v18.0</ALIAS>" to "<ALIAS>PLL Intel® FPGA IP v18.0</ALIAS> Custom Fields values: ['novalue'] Troubleshooting novalue False ['novalue'] ['FPGA Dev Tools Quartus® Prime Software Standard'] novalue 18.0 ['Programmable Logic Devices'] ['novalue'] ['novalue'] ['novalue']
