For example, if I click Edit page -> Edit in SharePoint Designer from within my SharePoint site, I'm always presented with a dialog prompting me to download Designer. I already have Designer installed.

Seems like it should a.) launch it for me, or b.) at least stop prompting me to download it.

UPDATE: Turns out this stemmed back to the 64-bit IE compatibility issue that was causing me grief here: How do I enable "Open in Explorer"?

    Can't say I've experienced this. Selecting Edit page in SharePoint Designer opens Sharepoint Designer for me. Have you made sure SPD is the default application for editing web pages? Commented Jan 19, 2012 at 21:21

Switching to 32-bit IE caused this to be a non-issue. I really wish Microsoft would look at the user-agent string and tell the user that stuff is going to be odd/disabled because they're running 64-bit, especially since most machines sold these days are 64-bit.

  • I read your answer about 64bit IE, causing the problem with Sharepoint Designer. How do you change to 32 bit, IE, as I have the exact same problem, with Sharepoint Designer 2010, in 64Bit IE? regards, Dan.

  • Nice idea. Lets see if I can fiddle this on top of pages as a warning (unless there is already a standard solution somewhere) Probably along : javascript:alert(navigator.userAgent.indexOf("MSIE 8.0") !=-1 && navigator.userAgent.indexOf("x64") !=-1); etc... will do
