Why am I getting "clearbox.exe has stopped working" when I run the ALTMULT_COMPLEX Megawizard?

Hi Dave,

It seems that "clearbox.exe" issue is with your specific machine and it might be due to Quartus temporary files so I would suggest you to take backup first & then remove the below suggested files,

Must take backup of all files first & keep it at different place/device

Perform the below steps,

1.Create a backup of following files located at “C:\Users\<user name>”

• quartus2.qreg
• quartus2.ini
• Remove these two files first, and then try re-launching Quartus

2.If the problem still persists please try same with “.altera.quartus” file located in same directory.

please update me , how it works for you.

Thanks,

Vikas
