After installing TurboTax 2019, I can no longer open older versions of TurboTax software, e.g., TurboTax 2018, that I had installed on my computer

I recently installed TurbTax2019 on my Windows desk top computer.   I have no difficulty opening and preparing my 2019 tax return.  However, I can no longer open the older versions of TurboTax that I had installed on my computer.   For example, when I click the icon for TurboTax 2018 on my desktop, the software will not open.   I saved the pdf version of my 2018 tax return and can open it, but I have always found it useful to look any of the various forms and worksheets from previous years that were not included as part of my e-filed federal or state returns.    I have always been able to access older versions of TurboTax on my computer.  Why can I no longer access them beginning this year.?
