Hi Richard,
This usually does the trick:
If none of the import/export wizards work at all, re-register
ACCWIZ.DLL.
If it's one or more file formats that aren't listed, re-register the
following files
msexcl40.dll (Excel)
msxbse40.dll (dBase)
mspdox40.dll (Paradox)
mstext40.dll (Text, CSV, tab-delimited))
In Access 97, the filenames contain 35 instead of 40.
To re-register a DLL file,
1) Locate it (usually all these are in the Windows\System32 or
WINNT\System32 folder.
2) Locate the file regsvr32.exe.
3) Drag the DLL file's icon onto the regsvr32.exe icon.
