Communicating with Excel

Having some issues communicating with Excel. I am currently using version 4.5_2 and am having problems with some very basic Excel write out function. Also am using a 64 bit workstation (Windows XP). I made a super simple model to start experimenting with using Excel spreadsheet and have written the following code to execute in on Entry trigger to a processor.

excellaunch("C:/Program Files (x86)/Microsoft Office/Office12");
excelopen("N:/Flexsim/P10/Boeing/1442 Work Flow/Flextest.xlsx");
excelsetsheet("Sheet1");
excelwritenum(1,1,69);
excelclose(1);
excelquit();

What happens is a GUI saying "An exception occured." and a path to a .txt file for details. The file says the following:

The object invoked has disconnected from its clients.

ExcelSetSheet: SheetName: _Sheet1_
----------------------------
----------------------------
ExcelWriteNum Row:1 Col:A Value:69.000000
----------------------------

Not sure what I am doing wrong or what the problem might be? Thanks for your assistance.

Turns out I didn't not properly close the spreadsheet the first time and added the correct command after I had already corrupted the connection. It works fine after rebooting...All apologies
