For one reason or another, you may find yourself in a position where QuickBooks needs to be reinstalled:
* QuickBooks won’t start anymore on your computer
* QuickBooks crashes because it can’t load pieces of its own program anymore
* Viruses or malware corrupted the QuickBooks installation on your computer.
* Your hard drive crashed and was replaced with a new hard drive
* You replaced your old QuickBooks computer with a new one
So you need to reinstall. Before you reinstall, however, there are two things you should do first:
Theoretically, reinstalling QuickBooks as per below shouldn’t do anything to your existing data. BUT, you can never be too careful, especially before performing system functions. So make a backup or your company data first. If you can’t run QuickBooks to make a backup, then make a copy of your company data with Windows, and copy it somewhere off your hard drive (a cloud drive, a USB drive, etc.) That way, if something goes really wrong with the reinstall steps, at least your data will not be lost.
If QuickBooks is already installed on your hard drive, you should first uninstall the existing QuickBooks installation before you install the software again.
Where do you do that? There is no uninstall option under your QuickBooks group in your Start List. So you uninstall it through Windows.
(The following shows how to do this with Windows 7. Other versions of Windows may be slightly different.)
Get to your Windows Control Panel. Click on Programs and Features. You will see a list of every program installed on your computer. Scroll down until you see your QuickBooks program in the list. Double-click it.
It will bring up the QuickBooks Maintenance Wizard. Click Next. You will see this:
Select Remove and finish.
QuickBooks will be uninstalled/removed from your computer.
[If your QuickBooks program was too badly damaged for the uninstall to work, then omit that step.]
Find your original install CD, or if you downloaded your QuickBooks program, the downloaded install file.
If your software is on a CD, insert it in your CD drive and follow the instructions to install it.
If you downloaded your QuickBooks program, then locate and double-click your downloaded QuickBooks install program and follow the prompts.
[If you don't know where you downloaded your QuickBooks program to, search your computer for setup_quickbooks to find the download file(s). One way to search (with Windows 7) is to press the Windows key on your keyboard, and then enter setup_quickbooks in the prompt that appears.]
If you don’t have the CD anymore, and/or you can’t find your download install file anymore, click here for links to download install files from Intuit.
At some point in the install process, you’ll be prompted for your product code and license number in order for the install to complete. You should have received those codes with your CD packaging, or if you downloaded QuickBooks, with your download order. If you don’t have the codes, you’ll have to call Intuit to get them.
After your product is installed, you’ll need to register it. Most of the time, you can do that without having to talk to Intuit.
After you’ve uninstalled, reinstalled, and registered QuickBooks, how does it work? Great, hopefully.
If not, here’s one more tool that might help.
