                                  • Hi,
                                    Check the project and the attached video

                                    When opening a xlsx file in a form with a spreadsheet and a ribbon an error occurs.

                                    If a ribbon doesn't exist the error desn't occur.

                                    For example in  Catalog2 the error occurs if you press the button. If you delete the ribbon and try again the error doesn't occur.

                                    If I save the xlsx fie to which the error occurs as xls it is opened in the sample project with no problem

                                    If the ribbon is created in previoyus versions I don't think that the error occus, because I have a form in my app with a ribbon already created
                                    to which the error doesn't exist.

                                    This error occurs both to 19.1.6 and 19.2.2 version

                                    Thanks,
                                    Manolis

                                  After may tests,
                                  I sealised that there is a problem or an option or a property with the new autocreated ribbon with spreadsheet.

                                  Find the difference.

                                  I'm attaching a new sample

                                  Open the last form Catalog4 and open an xlsx file . It opens correctly. I copied from a form,  from my app already created in a previous version

                                  Now open form Catalog2. The ribbon is created with 19.2.2 (19.1.6 behaves the same). Open an xlx file. The error occus.

                                  Hello Manolis,

                                  Your sample project reports numerous path-related errors on our machines. From what I gather, it is not necessary to use all these four projects to reproduce this problem. Would you please provide us with a small example demonstrating only this certain issue?
                                  Thanks in advance.

                                  Hi Paulo,
                                  I'm sending a clear new project.
                                  Please follow these steps.
                                  Run the project.
                                  Press the second button to open a form that contains a dpreadsheet and a ribbon created from the spreadsheet  (current version).
                                  Try to open an xlsx file.  I Include 2 xlsx files in the attachment. An error occurs.

                                  Press the third button. It opens  a form with a spreadsheet with only one button. Load the xlsx file. It opens correctly.
                                  Therefore is not a spreadsheet problem.

                                  Press the fourth button. It opens a form with a spreadsheet and a ribbon that I pasted from my application. This ribbon was created many versions before. I don't remember the exact version. Try to open a xlsx file. It opens correctly.

                                  Therefore the problem has to do (I think) with the new version of bars .

                                  I hope now I was clear enough.

                                  Many thanks,
                                  Manolis

                                  Hi ,
                                  Thanks for the patch.
                                  In one case that I wanted to implement there is still the error
