excel version at VI start

[Greg_Shipley]

I am using Win 2000 with LV6.1 I need to detect the version of Excel that is installed on the PC prior to starting Excel so I can remove the option to run Excel if the user does not have Excel 2000 installed. How do I do this? I tried an automation refnum and a version property node; however it does not return anything.

Read the registry keys. Check the image.

Joe's right. This is the only way to reliably do it. I run into this problem all the time. Everytime MS comes out with a new version of Excel, the ActiveX library changes and is no longer compatible with the LV ActiveX calls set up for previous versions, so you basically have to rewrite the code somewhat.

[Greg_Shipley]

does someone have some sample code on how to read the registry keys? ideally for EXCEL versioning.

[Joe_Guo]

there should be some examples of using registry keys.
