Excel auto opens twice
 

Wondering if someone could help. We have a hyperlink to an Excel spreadsheet
on one of our web pages.

Basically when launched some data is copied to the clipboard for the
launched sheet to use.

Problem being is that excel opens twice - first time copying the data from
the clipboard leaving it empty.

It then fails to load as the second time as excel tries to copy again from
the clipboard.

Is there a way of trying to stop this opening twice?

Tried excel /regserver avail.
