Excel 2007 slow to open files

I have been experiencing this for the last 48 hours after upgrading from 2000 to 2007.  Following the lead of another post, I looked at the addins - Excel Options>Addins.  The addins showed up under the Inactive header.  After using "Manage - Excel Addins" in that same window to install the current version, and restarting Excel (not the PC), my spreadsheets now open up quickly.  BTW, the Excel addins I have installed are:  Analysis ToolPak, Analysis ToolPak - VBA, Conditional Sum Wizard, Lookup Wizard, and Solver Add-in.  There are about 10 others still in the inactive section, but I am not worrying about those for now.

Hope this helps - mastman

I have this also on a few of my 200 already migrated computers.
All the same config or with some minor changes.
Happens randomly regardless of those changes.

Tried all steps mentionned in this thread without any success

If adding the add-ins doesn't work, I found that If I Immediately minimize the excel window by clicking the - in the upper right, it immediately closes and then reopens the window with the file opened.  Goofy.

likewise i found adding the add in lookup wizard seems to have fixed this fault..

Doesnt appear to make any sense because we now have about 200 users on office 2007 and this only seems to have affected a minority with no obvious reasons.

I also have this same issue with Excel 2007 taking forever to open and none of the aforementioned fixes seem to work.

I tried activating a few of the Excel Add-Ins as described by mastman and that worked very well for me.  Excel loads quickly now when opening notebooks both from the local hard drive and on a network share.  The environment was Windows XP Pro and MS Office Small Business Edition.

I was having this problem for all my new computer roll-outs with Office 2007.  when opening an attached Excel file it would take several minutes in what should be a few seconds.  The solution for me was to open outlook, open the email with an excel attachment.  then click on the attachment ONCE and outlook will install the preview excel items it needs.  You only need to do this once and it is fixed forever on all excel attachments!!!!

I just want to say, I have been looking in many places and the question itself mentioned the key to solving the problem for me which is replacing the /e with"%1"

I have tried adding the "%1" at the end like many other posts suggested but that never worked



So thanks a million for the owner of this question !! :)

I had this problem, and the easy, and unlikiely fix, was to enable the Lookup Wizard in Excel.  Believe it or not, once I did this we could open spreadsheets from mail attachments no problem.  Give it a try! :)
