Can't open Q17.0 Standard project because it is seen as a "Pro directory structure"

Hi,

You cannot open/compile design created in Pro edition in Standard edition. You can migrate a design from Standard edition to Pro edition but not the other way around. You may create a new project in the Standard edition and add those required files in the project directory.

To compare both editions, refer to https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/po/ss-quartus-comparison.pdf

Thanks.
