Calling LoadLibraryEx on ISAPI filter

[hamedkh]

Hi,

I get following error on one of my sites on plesk 11:
HTTP Error 500.0 - Internal Server Error
Calling LoadLibraryEx on ISAPI filter "C:\Program Files (x86)\Parallels\Plesk\Additional\PleskPHP5\php5isapi.dll" failed

I checked and application pool "enable 32bit applications" was true!
this problem happens when PHP runs for ISAPI when we change it to FAST CGI problem solves, but we need ISAPI
