I found this via google. Is this the only way to do this? Used to be in the [MarketingMessages] block of Quicken.ini file. (Where is the *.ini file now anyway?)
Quicken still has ads. The only way you could suppress them (in 2004 anyway) was to rename the *dat files that the ad copy pulled from.
Quicken has changed the way they've done these in 2005. While the data is still in *.dat files, if you delete them now, the program will re-create them.
Easiest way (although a bit time-consuming) is to modify the files.
Path is (assuming your operating system is on your C: drive): C:\Documents and Settings\All Users\Application Data\Intuit\Quicken\Inet\Common\Alerts\fn
Open the *.dat files in Notepad and delete the information under the [DisplayData] heading.
The same files appear under C:\Documents and Settings\All Users\Application Data\Intuit\Quicken\Inet\Common\Pnf\Quicken as well, so you might want to edit them there as well.
While it's a bit of work, it's kept ads from displaying for me.
