Description:
------------
On my WinXP computer with Office 2003 all work correctly, php-script (see it in 
section 'test script') generates ms-excel file 1.xls. But on the computer with 
windows2008server this php-script generates an error: 

Fatal error: Uncaught exception 'com_exception' with message '<b>Source:</b> 
Microsoft Office Excel<br/><b>Description:</b> Невозможно получить свойство Save 
класса Workbook' in C:\www\prj\1.php:12 Stack trace: #0 C:\www\prj\1.php(9): 
variant->Save() #1 {main} thrown in C:\www\prj\1.php on line 9

My php installed as an apache handler.

How to solve it?

Test script:
---------------
$x = new COM("Excel.Application");
$x->Application->Visible = 1;
$x->Workbooks->Add();
$x->ActiveSheet->StandardWidth = 5;
$r = $x->Range("a:a");
$r->Select();
$rc = $x->Selection();
$rc->ColumnWidth = 50;
$x->Workbooks[1]->SaveAs("c:/1.xls");
$x->Quit();
$x->Release();
$x = Null;
$r = Null;

Expected result:
----------------
File 1.xls must be generated and saved into C:\

Actual result:
--------------
Fatal error: Uncaught exception 'com_exception' with message '<b>Source:</b> 
Microsoft Office Excel<br/><b>Description:</b> Невозможно получить свойство Save 
класса Workbook' in C:\www\prj\1.php:12 Stack trace: #0 C:\www\prj\1.php(9):
