Downloaded php4.04 and installed in c:\php directory over a working copy of 4.02

Try to do a mssql_connect and get

'The procedure entry point php_unregister_ini_entries could not be located in the dynamic link library php4ts.dll.'

dll is dated as 20th Dec 2000, 11:01 same as php.exe and is present in c:\php only

Press ok on this box and get...

'Unable to load dynamic library './php_mssql70.dll' - The specified procedure could not be found.'

Then get on page:

I hope that this is enough info to go on.  If I back out to v4.0.2 then everything works ok again, but I want to use the file upload stuff in the new version which is why I want to upgrade.

Cheers,

David Clark.
