external component modified since last VI save

[uzoyabuzo]

Hi !!

it's been quite a bit that I'm stuck with this message "External component modified since last VI save". One explanation on the forum does not solve my problem.

The problem is :

I have a simple VI (enclosed) that I open on two different computers. Each time I save it on one computer and I open it on the second one Labview shows the mysterious message "External component modified..."... and I have to save the VI... Back to the first computer - same thing...

Does anyone know where should I search to get rid of this message ?

Thanks for any suggestions...

You had asked basically the same question a while ago.

You probably have two different versions of Excel on each computer. Or, you have one with a different service pack.

........No, I've checked that... same version of excel on both computers and same SP... any other hints ? Thanks anyway...

Hello,

Maybe it is the difference of the operating systeme, do you use the same operating systeme on both computers? (Windows XP, Windows 7)?

...Same OS on both computers XP Pro SP3...

Ok,

What does your application do anyway? It could be a problem of the Active X Refernces

[uzoyabuzo]

My application opens Excel, creates a workbook and etc and then sends a 2D array... Yes, the problem seems to come from a different component somewhere (probably in the Active X references as you said), but I don't really know where to search...

Do you open and close every Reference correctly?

[uzoyabuzo]

Yes, references are opened and closed the same way...

In fact my problem is summarized in the VI I enclosed in my first post... There's one computer that has a different configuration from others here, and when I open that Vi on that computer Labview asks to save it before close (external component modified). I've checked the OS, the Excel version, ...

Do have the same Versions of LabVIEW on both Computers? (Version, Service Pack, Patch, Language, Toolkits, Drivers)
