This is working here. The code of @leuce too. My problem is solved. Thanks for your help and support.

Ok, thank you. No errors here. "test.xlsx" is hidden, Excel too. Excel is only visible in the Task Manager.

@Danp2I have looked at the help file entry for "_Excel_Open". This is the code to launch a hidden copy of Excel: #include <Excel.au3> Global $bVisible = True Global $sWorkbook = "C:\test\test.xlsx" $oWorkbook = _Excel_BookOpen(_Excel_Open($bVisible = False), $sWorkbook) After that, what to do to minimize the file?

@Danp2 Thank you for the information. How can you do that?

I have seen the topic "Excel Management" in the help file. It seems that there is no "@SW_MINIMIZE" with "_Excel_BookOpen".

This is working: ShellExecute("Excel.exe", "", "", "", @SW_MINIMIZE) Excel UDF?

Neither of them works. Excel is my default app for .xlsx files on my PC.

@SW_MINIMIZE does not work here. What's wrong? ShellExecute("Excel.exe", "C:\test\test.xlsx", "", "", @SW_MINIMIZE)

I upgraded SandBoxie 5.18 to 5.20, my problem is solved! Thank you for your help @Danp2!

Yes, I'm using SandBoxie (version 5.18) @Danp2.

@Wanarmal, running SciTE as Administrator is not solving my problem.

The text "Klasse is niet geregistreerd" is Dutch and means "Class not registered". My output:

Thank you for your script @Danp2.

Using Global instead of Local will not solve this problem.

When I want to test Example 1 of Function _IECreate (AutoIt Help File), I see that function _IECreate doesn't work in Windows 10. Syntax Check (Ctrl+F5) gives no errors. Example 1: ; Create a browser window and navigate to a website #include <IE.au3> Local $oIE = _IECreate("www.autoitscript.com") The error I receive with F5 (Tools, Go) in SciTE:
