Delphi Registration Failing

26

I don’t know if this will be any help …
A few times when I’ve had new Delphi’s, some old versions get registration problems.
This info was in an email from Emb in 2020 :

It is possible the installation is detecting a corrupted or outdated license file. Either because of previous version serial numbers you have registered that has no subscription or previous trial licenses you have used that is being detected by the registration.

Please do the steps to clear licenses that could cause issues with the install.

  1. Remove any .slip or reg.txt files located in the following directory:
    C:\Users<your user name>

  2. Delete or rename the directory below (note that this will also delete the existing serial number in the License Manager which you can simply re-register later):

C:\ProgramData\Embarcadero

  1. Clear out and delete all files and folders in your temp folder:

C:\Users<your user name>\AppData\Local\Temp

  1. Perform a complete manual uninstall of 10.2 Tokyo:

  1. Re-install the product and re-register your paid license.

It’s not fun … :frowning:
