My Client is trying to open a 100MB excel export of report. After clicking OK, Excel stays open but does not open the document.
More aboutproblem excel
Get a bit more specific please! What is an "excel export of report"? And how does he opens it?
Definitely more info please. What is the file extension of the file he's trying to open? How was it created, ie version of software used to create it, name of software etc. What version of Excel is being used to try and open it?
100MB is a large file, Excel is going to require quite a bit of time to open it. 2 or 3 minutes wouldn't be out of the question (longer on a resource starved machine). Just relax and let it do its thing.
