I am a senior financial manager in a well-reputed company and using Quicken for maintaining the accounting records of my daily based business in Quicken. I have rich experience of using the advanced features of Quicken, so I am very comfortable to use Quicken properly. While working on Quicken, I am experiencing Quicken error code 1618. This error code takes place due to the problems in the running time. This error code takes place, when the program files infected due to the internet threat. So, I am not able to resolve this error code. I don’t have the actual reasons of this error code. Can anyone recommend the easy methods to fix this error code?
