I installed Quicken 2006 H&B Premier on a Vista Ultimate x64 machine without any apparent problem and even downloaded its updates. But when I try to run it, it asks if I want to use an existing file--I check yes--then it crashes and generates an error report to send to MS.
Googling for this doesn't reveal anybody else having this significant a problem with Quicken and x64 Vista but I wonder if this group can offer a solution.
