Requirements
- Install Excel Report. The Excel Report is part of the base installation.
 - Windows Operating System
 - Correctly installed version of MS Excel - see chapter Software requirements.
 - The Microsoft Sub installation MDAC 2.7 (that is a superset of ADO) is executed instead if it is required for the use of a feature and it is not installed yet.
 - Use of the "History DB" (WCCOAvalarch), "RDB Archiving" (WCCOArdb) or NextGen Archiver (NGA).
 - You will need your own license to run Excel Report.
 - The following files are included with WinCC OA and are located in C:\Windows\System32\ or in the installation
          directory of WinCC OA:
          
- mscomctl.ocx
 - mscomct2.ocx
 - SubTimer.dll
              Note:If an error occurs during the installation of WinCC OA, a manual registration of the library (SubTimer.dll) must be performed. Open the command prompt as administrator and execute c:\Windows\SysWOW64\regsvr32.exe <NAME>.dll.
 
 
CAUTION: 
       Note that if you use statistical functions and
        have specified the "Always start calculation at" time on the synchronization tab of the data
        point function, the start time for the report has to be the same as the "Always start
        calculation at" time of the DP function (otherwise, the report won't get the required
        data).
CAUTION: 
      The correct installation
        order of Office and WinCC OA is very important, otherwise the
        functionality of Excel Report is not granted and some errors may occur. Install Office first
        and WinCC OA afterwards. Furthermore, please keep in mind that you have
        to reinstall WinCC OA if you update your Office version.
Note: 
    To be able to use the Excel report in the
        example projects (Demo
          Application and Getting
          Started), you have to copy all files from the
          <wincc_oa_path>\data\xls_report to
          <proj_path>\data\xls_report.
Restriction: 
   The Excel Report does
            not work with NextGen Archiver (NGA).
