Install missing RICHTX32.OCX file

NATools programs use Visual Basic.  Until recently, Microsoft automatically installed the VB runtime library when Windows was installed.  With recent versions of Windows, that no longer happens, and you need to get the missing library, or at least the RICHTX32.OCX file.  Here's how:

For 32-bit Windows:

• Right-click this link:  RICHTX32.OCXDAT file from here
• Select "Save As" and save it as RICHTX32.OCX  (leave off the DAT)
• Copy it to c:/windows/system32
• Click Windows Start icon at bottom left
• Select All Programs, then Accessories
• Right-click Command Prompt, then select "Run as administrator"
• In the command prompt, type:  regsvr32 c:/windows/system32/RICHTX32.OCX

For 64-bit Windows 7 or later:

• Right-click this link:  RICHTX32.OCXDAT file from here
• Select "Save As" and save it as RICHTX32.OCX  (leave off the DAT)
• Copy it to c:/windows/syswow64
• Click Windows Start icon at bottom left
• Select All Programs, then Accessories
• Right-click Command Prompt, then select "Run as administrator"
• In the command prompt, type:  regsvr32 c:/windows/syswow64/RICHTX32.OCX
