I Get a Similar issue
SENIOR MOMENT ALERT!
Should have read the error message, the clue is in the question!!
to resolve the problem go into the php.ini file and uncomment this entry ;extension=php_curl.dll (remove the preceding semicolon)
Once I did this all was well and I can now install to my hearts content.... sorry for being old and tired ;-))
I have attached a screenshot. For the the problem is not the incorrect wording but the fact that I get the following error message:
ERROR: PowerCMS cannot activate without cURL installed and functional on your PHP server. Please activate cURL before attempting to proceed.
This is displayed when no serial number is inserted but even when I put my PowerBuilder serial number it stays red.
The site I am installing to is a mature one which until now has not had any PHP on it.
