when deploying site production server getting following error -

retrieving com class factory component clsid {00024500-0000-0000-c000-000000000046} failed due following error: 80070005 access denied. (exception hresult: 0x80070005 (e_accessdenied)).

to resolve issue have applied following solution not working - @ of link mentioned publish application 32-bit or 64-bit, developed asp.net website no option 32-bit , 64-bit. @ iis have "enabled 32-bit application" true.
