In trying to use the Tax Planner, Quicken goes through the following gyrations:
"Please wait while Windows configures Quicken. … Gathering the required information. … The feature you are trying to use is on a CD-ROM or other removable disk that is not available. Insert 'Quicken' disk and click OK."
Since there is no longer a Quicken disk, it results in "Error 1706. No valid source could be found for product Quicken. The Windows Installer cannot continue." Quicken then goes into a continuous loop asking for the same thing.
I have used the Tax Planner every year about this time. In trying to use it today for the first time this year, 12/4/25, I have run into this problem for the first time.
I am currently using: Quicken Classic Premier for Windows Version R65.17, Build 27.1.65.17
Windows 11 Home, Version 24H2, Quality Update: 2025-11 .NET 8.0.22 Update for x64 Client (KB5071066)
