Dear Sir, I'm still have problem installing osCommerce even after download and installed PHP ver 4.3.5 , all steps and procedures are followed according to instructions but still stuck after typing url http://localhost/catalog/install/index.php. Using OS Win XP Professional. Web Server :Microsoft IIS ,running PHP as CGI Already installed Mysql s/w and download osCommerce s/w but can't configure with PHP localhost and web server. Source Code in blank screen of IE 6 browser look like this :- <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN"> <html> <head> <style> a:link {font:8pt/11pt verdana; color:red} a:visited {font:8pt/11pt verdana; color:#4e4e4e} </style> <meta HTTP-EQUIV="Content-Type" Content="text-html; charset=Windows-1252"> <title>HTTP 500 Internal server error</title> </head> <script> function Related(){ userURL=document.location.href; //for the href, we need a valid URL to the domain. We search for the # symbol to find the begining //of the true URL, and add 1 to skip it - this is the BeginURL value. We use serverIndex as the end marker. BeginURL=userURL.indexOf("#",1) + 1; CurrentURL=userURL.substring(BeginURL,DocURL.length); //Build the query RelatedServiceURL="http://related.msn.com/related.asp?url="; //Perform simple check for Intranet URLs //this is where the http or https will be, as found by searching for :// but skip res: protocolIndex=userURL.indexOf("://",4); serverIndex=userURL.indexOf("/",protocolIndex + 3); urlresult=userURL.substring(0,serverIndex); if (protocolIndex - BeginURL > 7) urlresult="" //Check if Intranet URL - then open search bar if (urlresult.indexOf(".",0) < 1) userURL="Intranet URL"; finalURL = RelatedServiceURL + encodeURIComponent(userURL); window.open(finalURL, "_search"); } function Homepage(){ // in real bits, urls get returned to our script like this: // res://shdocvw.dll/http_404.htm#http://www.DocURL.com/bar.htm //For testing use DocURL = "res://shdocvw.dll/http_404.htm#https://www.microsoft.com/bar.htm" DocURL=document.location.href; //this is where the http or https will be, as found by searching for :// but skipping the res:// protocolIndex=DocURL.indexOf("://",4); //this finds the ending slash for the domain server serverIndex=DocURL.indexOf("/",protocolIndex + 3); //for the href, we need a valid URL to the domain. We search for the # symbol to find the begining //of the true URL, and add 1 to skip it - this is the BeginURL value. We use serverIndex as the end marker. //urlresult=DocURL.substring(protocolIndex - 4,serverIndex); BeginURL=DocURL.indexOf("#",1) + 1; urlresult=DocURL.substring(BeginURL,serverIndex); //for display, we need to skip after http://, and go to the next slash displayresult=DocURL.substring(protocolIndex + 3 ,serverIndex); // Security precaution: must filter out "urlResult" and "displayresult" forbiddenChars = new RegExp("[<>\'\"]", "g"); // Global search/replace urlresult = urlresult.replace(forbiddenChars, ""); displayresult = displayresult.replace(forbiddenChars, ""); document.write('<A target=_top HREF="' + urlresult + '">' + displayresult + "</a>"); } function doSearch() { saOC.NavigateToDefaultSearch(); } function initPage() { document.body.insertAdjacentHTML("afterBegin","<object id=saOC CLASSID='clsid:B45FF030-4447-11D2-85DE-00C04FA35C89' HEIGHT=0 width=0></object>"); } </script> <body bgcolor="white" onload="initPage()"> <table width="400" cellpadding="3" cellspacing="5"> <tr> <td id="tableProps" valign="top" align="left"><img id="pagerrorImg" SRC="pagerror.gif" width="25" height="33"></td> <td id="tableProps2" align="left" valign="middle" width="360"><h1 id="errortype" style="COLOR: black; FONT: 13pt/15pt verdana"><span id="errorText">The page cannot be displayed</span></h1> </td> </tr> <tr> <td id="tablePropsWidth" width="400" colspan="2"><font style="COLOR: black; FONT: 8pt/11pt verdana">There is a problem with the page you are trying to reach and it cannot be displayed.</font></td> </tr> <tr> <td id="tablePropsWidth" width="400" colspan="2"><font id="LID1" style="COLOR: black; FONT: 8pt/11pt verdana"><hr color="#C0C0C0" noshade> <p id="LID2">Please try the following:</p><ul> <li id="instructionsText1">Open the <script> Homepage();</script> home page, and then look for links to the information you want. </li> <li id="instructionsText2">Click the <a xhref="javascript:location.reload()" target="_self"> <img border=0 src="refresh.gif" width="13" height="16" alt="refresh.gif (82 bytes)" align="middle"></a> <a xhref="javascript:location.reload()" target="_self">Refresh</a> button, or try again later.<br> </li> <li ID="instructionsText3">Click <a href="javascript:doSearch()"><img border=0 src="search.gif" width="16" height="16" alt="search..gif (114 bytes)" align="center"> Search</a> to look for information on the Internet. </li> <li id="instructionsText4">You can also see <a onclick="Related();event.returnValue=false" href="">a list of related sites.</a> </ul> </p> <p><br> </p> <h2 id="ietext" style="font:8pt/11pt verdana; color:black">HTTP 500 - Internal server error <br> Internet Explorer </h2> </font></td> </tr> </table> </body> </html> I think my web server is not setup and running properly yet, I can't see any output screen, it 's blank screen that means to say I've not install my PHP & configured properly my php.ini file for web server ??? Secondly the Catalog folder is placed at C:/Inetpub/wwwroot as per nstallation notes on installing PHP and MySql under Windows with doc_root =c/Inetpub/wwwroot in edited in php.ini I can configure from Admin Tool --->Internet Info Services , etc in Win XP Professional but later stage when I uninstall and reinstall PHP s/w, I can't configure again no matter how many times I click at Start--->Admin Tool --> IIS ....it's doesn't work anymore . I'm confused and frustrated perhaps, pls help and advise what the best solution else how to install osCommerce configured with localhost http://localhost/catalog/install/index.php. where localhost web server is Microsoft IIS and catalog located at c:/Inetpub/wwwroot. Thank you for reading and trying to help solve this technical bug error.
