Sorry, the separate download for 2020.17 is not yet available - the initial release had terrible problems that we are still working through! Hopefully later in the week.
I have to say though your problem is unique in my experience; even people who can't uninstall the launcher in Windows can usually install the new one anyway.
I was out of luck, and I don't know why it had to make me delete the old launcher.
Hopefully this issue will be resolved in the new launcher. Please don't forget me if the new launcher comes out.
1.When the installation progresses to a certain point it will ask me to remove the old launcher
2.It asks me to delete the old launcher even though I have deleted it and do not have the old launcher, and if I follow the prompt it will show that it is not the installer
3.When I tried to close the launcher prompted that the old launcher could not be removed, please contact the technical team
4.When I repeated it three times the launcher did not skip this part and it showed that the installer had ended prematurely because of an error
The launchers are shown in the following order. I copied them over:
The feature you are trying to use is on a network resource that is unavailable.
Click OK to try again, or enter an alternate path to a folder containing the installation package "launcher-installer-windows. msi in the box below.
The older version of Paradox Launcher v2 cannot be emoved. Contact your technical support group.
Paradox Launcher v2 Setup Wizardended prematurely
Paradox Launcher v2 Setup Wizard ended prematurely because of an error. Your system has not been modified. To install this program at a later time, run Setup Wizard again.Click the Finish button to exit the Setup Wizard.
Even though I have completely deleted it and done everything you asked, the launcher still shows the above repeatedly and cannot skip this stage.
