I've been using MS Office Professional 2003 (SP3) with no problems for years. I'm using Windows XP Pro SP3. Ample RAM and disk space. Suddenly today Excel will not start but gives a 'Not Enough Memory to run Microsoft Office Excel' message. It is not related to any specific .xls, but to the application itself. Word, Access and Outlook start and work o.k. Publisher, Powerpoint and OneNote also will not start. OneNote gets into a loop, repeatedly presenting the Send error report to Microsoft dialog.
The offer to start in Safe Mode also fails (same message). Attempts to Repair Excel fail, after inserting the original MS Office Pro CD, with an Error 1326 'Error getting file security C:\Program Files\Microsoft Office\OFFICE11\GDIPLUS.DLL GetLastError: 5'
Rebooting windows makes no difference. Other applications appear to function normally --only Office programs are affected.
Help! I'm at a loss as to what the cause could be and what to do about it.
