Convert Quicken 8 for DOS data to Quicken 2012 for Windows
I contacted Quicken support today, and the correct way to convert is set out below:
I would like to inform you that you can convert your Quicken for DOS version data into Quicken 2012 program. For this, you need to install Quicken 99 and then Quicken 2004 as intermediate versions.
First, install Quicken 99 version as an intermediate. After installing, please convert your data into Quicken 99.
After converting you data to Quicken 99, please install Quicken 2004. After installing Quicken 2004, you can convert your Quicken 99 data into it.
After your Quicken data is converted to Quicken 2004, please install the Quicken 2012 Program and convert the data file of Quicken 2004 into Quicken 2012 program.
Note: Before converting, please be ensure that Quicken 2012 version should be Deluxe or higher as Quicken 2012 Starter Edition does not have the capacity to convert the data file from earlier version of Quicken.
To install Quicken 99 and more details, please follow the below mentioned link:
