Can I install or use Quicken on a network?
Quicken is not designed to be used over a network or shared drive. Due to the many possible network configurations, Quicken doesn't offer technical assistance for this type of configuration.
Quicken incrementally saves your data as it's entered. Saving Quicken data files locally (directly on your computer's hard drive), and not over a network, decreases the risk of data loss. Network instability or the use of a single data file by multiple people at the same time will often lead to data integrity issues.
If you'd like to use your Quicken data file on different computer systems, you'll need to install Quicken on each computer. If you'd like some help, check out Installing Quicken on Multiple Computers.
