Excel X64 -thethingy- — Microsoft Office 2010

Microsoft Office Excel 2010 x64 is the 64-bit build of Excel 2010, released as part of Office 2010. It was designed to take advantage of 64-bit processor architectures and larger system memory, providing improvements for heavy-duty calculation, very large workbooks, and advanced data models compared with the 32-bit edition.

Title: *Looking for MS Office 2010 Excel X64 -thethingy- (The old Data Analysis pack?) *

Hey everyone,

I know this is a long shot. I maintain an old wind turbine monitoring system running on Windows Embedded 7. The software specifically relies on Microsoft Office 2010 Excel X64 and what the old engineers called "-thethingy-".

I believe "TheThingy" refers to the 64-bit version of the Solver Add-in or possibly the deprecated MS Query connector. In newer versions of Excel, the macro throws a "Type Mismatch" error because the DLL registration fails.

Questions:

Current Error: "Run-time error '429': ActiveX component can't create object" – That’s TheThingy failing to load.

Help me save this turbine from an expensive $50k upgrade!

TL;DR: Need the specific X64 ActiveX control for Excel 2010. MICROSOFT OFFICE 2010 EXCEL X64 -thethingy-


Before 2010, Excel was a prisoner. It was locked inside a 32-bit memory address space, meaning it could only utilize 2 GB of RAM (or 4 GB with tricks). For a financial modeler trying to process 1.5 million rows of data, Excel would hit the "Out of Memory" error faster than you could press Ctrl+S.

MICROSOFT OFFICE 2010 EXCEL X64 -thethingy- shattered that ceiling. For the first time in history, Microsoft released a version of Excel that could address up to 8 TB of virtual memory. Suddenly, the 2GB wall was gone.

In Excel 2010 x64, the maximum array size is limited not by address space but by available memory + contiguous memory. A frequent issue: Microsoft Office Excel 2010 x64 is the 64-bit

Workaround: Use Excel’s worksheet ranges or .NET/COM interop for larger datasets.


.xlsx files are architecture-agnostic. A file saved in 64-bit Excel opens fine in 32-bit – unless it contains VBA with PtrSafe calls that fail on 32-bit.


  • COM add-ins: Recompile or obtain 64-bit versions of add-ins; for unmanaged code, build with /LARGEADDRESSAWARE and provide 64-bit binaries.
  • Drivers and ODBC/OLEDB: Use 64-bit data providers when connecting to external databases; 32-bit drivers won’t work with 64-bit Excel.
  • Third-party integrations: Test integrations with SharePoint, database connectors, and reporting tools before switching.
