error detected by export dll

[AndresLuis]

Hi,

I have a problem exporting to Excel data only format. Error detected by export dll. I have a version of crystal reports 11.5.3.417. My operating system is windows 11 pro. When I export to Exel format it doesn't fail, it only fails when I export to Excel data only format. In the report there are some fields of SQL expressions type. If I remove any of these expressions then it doesn't fail. But the expressions are very simple, they are of the type (select field from table1).

How can I resolve the error?

thanks.

You stated that "If I remove any of these expressions then it doesn't fail.".
Did you mean to say If I remove all of these expressions then it doesn't fail?

Can you replicate the problem with a simple report using the Xtreme sample database?
If so, please upload that rpt file.  Add a .txt extension to allow the upload.

I want to say some of them, "expressions"
