It was running before and I have Apache successfully running on WinXP when trying to open localhost. When I try to run http://localhost/ I get this error: Error signature AppName: php.exe AppVer: 4.3.0.0 Offset: 57565553 Error report shows: <?xml version="1.0" encoding="UTF-16"?> <DATABASE> <EXE NAME="php.exe" FILTER="GRABMI_FILTER_PRIVACY"> <MATCHING_FILE NAME="php.exe" SIZE="45056" CHECKSUM="0x64B01181" BIN_FILE_VERSION="4.3.0.0" BIN_PRODUCT_VERSION="4.3.0.0" PRODUCT_VERSION="4.3.0" FILE_DESCRIPTION="PHP Script Interpreter" COMPANY_NAME="The PHP Group" PRODUCT_NAME="PHP Thread Safe CGI" FILE_VERSION="4.3.0.0" ORIGINAL_FILENAME="php.exe" INTERNAL_NAME="php-cgi" LEGAL_COPYRIGHT="Copyright © 2002 The PHP Group" VERFILEDATEHI="0x0" VERFILEDATELO="0x0" VERFILEOS="0x4" VERFILETYPE="0x1" MODULE_TYPE="WIN32" PE_CHECKSUM="0x0" LINKER_VERSION="0x40000" UPTO_BIN_FILE_VERSION="4.3.0.0" UPTO_BIN_PRODUCT_VERSION="4.3.0.0" LINK_DATE="12/27/2002 04:33:57" UPTO_LINK_DATE="12/27/2002 04:33:57" VER_LANGUAGE="English (United States) [0x409]" /> </EXE> <EXE NAME="kernel32.dll" FILTER="GRABMI_FILTER_THISFILEONLY"> <MATCHING_FILE NAME="kernel32.dll" SIZE="926720" CHECKSUM="0x6262EEA5" BIN_FILE_VERSION="5.1.2600.0" BIN_PRODUCT_VERSION="5.1.2600.0" PRODUCT_VERSION="5.1.2600.0" FILE_DESCRIPTION="Windows NT BASE API Client DLL" COMPANY_NAME="Microsoft Corporation" PRODUCT_NAME="Microsoft® Windows® Operating System" FILE_VERSION="5.1.2600.0 (xpclient.010817-1148)" ORIGINAL_FILENAME="kernel32" INTERNAL_NAME="kernel32" LEGAL_COPYRIGHT="© Microsoft Corporation.
