Hi all!! I don't know if this is the right forum, but we have a situation in our client that start to be annoying. PC's with Win 7 64 bits + Office 2010 prof., opening some files over the network takes a loooooooot of time... PC's with XP and Office 2003 all ok.. Instant opening. What can be wrong? Thank's in advance CoreCore

I found the below article that helped in our environment. I hope it helps you out as well. *Note* the instructions are for office 2007 but I'm fairly certain the same thing applies to 2010. http://www.jacobdybala.com/slow-opening-excel-2003-files-in-excel-2007 Thanks,
