how do i install my quicken account on a reimaged laptop
To get the current Quicken software reinstalled, log into your account at Quicken.com and download the Quicken Windows installer. It won't bring back your data file though so I hope you have a backup of that somewhere.
If you were using an older version of Quicken Windows, you can find the last 9 years of updates here:

If you were using one older than that then I'm not sure what your options are.
