Microsoft Office 2010 Excel X64 -thethingy- !link! May 2026

Given the broad nature of your query, I'll provide a general guide on how to navigate and use some key features in Microsoft Office 2010 Excel x64. If "-thethingy-" refers to something specific, please provide more details, and I'll do my best to assist you.

3. The "No Turning Back" Rule

Once you installed the X64 version, you could not open a workbook that used 32-bit specific tools. It was a one-way door.

8. Hands-On Example: Loading a 1.5 GB CSV

Let’s simulate a typical 2010 scenario: MICROSOFT OFFICE 2010 EXCEL X64 -thethingy-

User: Data analyst with a 1.5 GB server log file.

32-bit Excel:

• Open CSV → “Excel cannot open this file because it exceeds the maximum size.”
• Or opens partially → then crashes on sort.

64-bit Excel 2010:

• Open CSV → takes 90 seconds to load.
• Memory usage in Task Manager: 1.8 GB.
• Apply filter → responsive.
• Build PivotTable → 20 seconds.
• Save as .xlsx (compressed to 600 MB) → no crash.

This was the “thingy” magic.

A. The WIN64 / Win64 VBA Compiler Constant

If you are working with VBA (macros) and see code like:

#If Win64 Then
    ' 64-bit specific API declarations
#Else
    ' 32-bit specific
#End If

That is a compiler constant unique to Office 2010 x64. It helps manage Declare PtrSafe statements for Windows API calls. Given the broad nature of your query, I'll

Example: GetTickCount

#If VBA7 Then
    #If Win64 Then
        Declare PtrSafe Function GetTickCount64 Lib "kernel32" () As LongLong
    #Else
        Declare PtrSafe Function GetTickCount Lib "kernel32" () As Long
    #End If
#Else
    Declare Function GetTickCount Lib "kernel32" () As Long
#End If

Without PtrSafe and LongLong/LongPtr, macros crash — a common “thingy” for people upgrading from Excel 2003/2007. Open CSV → “Excel cannot open this file
