      Hi Su,

      Thank you for contacting us about this issue.

      I kindly ask you to open the '%localappdata%\The Welkin Suite\Installation' folder and check if the .NET installer and the 'TheWelkinSuiteComponentsHash.txt' file are present here. Please let us know about this since this can help us in our investigation related to a reason for this issue.

      After this, please delete all the files in the folder and launch TWS installation again.

      The reason for the issue is that we couldn't check the integrity of the .NET installer using a hash file since this file does not exist or it is corrupted.

      If the issue would be reproduced again, please follow the next steps:

           1. please open this link;

           2. save the file;

           3. open the 'Installation' folder again and paste the file into this folder; if the file already exists, please replace it.

      Please let me know if this would help to continue TWS installation.

      Thank you,
