Ever get error code "-2146827284" when trying to open an Excel workbook using ActiveX

[Bmarsh]

The error message claims that the file cannot be found, but the file is clearly there. Ever seen this?

Strangely, this happens on one machine, but not on another. I'm suspecting some kind of ActiveX incompatibility and would love suggestions on how to track this bugger down (I submitted to support also).

Thanks

Brad

The attached vi exhibits this behavior (on one machine anyway)...

Brad,

My suggestion is that if you know exactly where does your Excel ActiveX Library resides, please look for it and re-register it in windows, using the regsvr32 command. If not, please check wether the Excel version of the machine that is having problems is the same version as the machine where it is actually working. Last resource you may want to try to reinstall Excel after trying some of the Excel examples that came with LabVIEW. If you feel that you need more direct assistance please contact us directly, you may wish to call us or email us and you can find the information for doing so at www.ni.com/ask in the internet.

Good luck!
