Hi Thomas,

I have installed the newest version of DW from the download webpage (MD5 checked).

It is installed without any error. But when I double-clicked the icon, nothing happened. I tried to start it from the command, but no error message was given. I have also checked java version. Nothing seems to be wrong. I just installed this OS last week, so I don't have any other virus-defender apps except the Microsoft firewall itself. Is there any solution?

It looks like DataWarrior is prevented from starting, either by the OS itself or by some security software.

Although I have never seen that with the DataWarrior installation, please try this: Open the Properties window of DataWarrior.exe and check if you see an unlock checkbox somewhere at the right bottom of the dialog, which you need to select to allow this file to be executed.

Hi Thomas,

Thank you very much for your reply. It works fine now. It seems to be a Java common problem. I installed the 64-bit Java 8. And I have to manually add the Java \bin file path to the top of the OS environment path.

I think some OS could probably raise a warning like 'could not find java.dll', but mine didn't. So it took me some time to figure out what is the issue. But anyway, it works fine now! Thank you for this amazing software.

Anna

Hello Anna,

because the download page[1] states

«All installers on this side include the Liberica OpenJRE 8_282 from BellSoft. Thus, there is no need to install any Java software yourself.»

possibly DataWarrior uses /this/ Java runtime without regard if there is an other already present and typically used (e.g., openjdk[2] in Linux Debian) ahead of DataWarrior's installation, or not.
