Could not find file Thread.xlsx

[alex_hiis6PJP6]

Hello

Problem with accessing thread data after migrating to Inventor 2025.

In the screenshot I have shown that the thread.xlsx file is in the correct folder, but for some reason Inventor can't locate it.

It is strange that file looks like MSExcel 97-2003

It should be *.xlsx with other size

Try to save it in new format.

I just experienced this same issue.

Autodesk has changed the following files for Inventor 2025 to use ".xlsx" files instead of ".xls" for the clearance.xls, thread.xls, bend table (mm).xls, and bend table (in).xls.

I opened the file and resaved it as .xlsx and it worked.
