As of TCIA/NBIA 6.5.3, manifest files are self-contained and only version 3.0 and later of the NBIA Data Retriever can read it. Please update your app.

Two versions of NBIA Data Retriever in application list

Why, after I upgrade the NBIA Data Retriever, do two versions of it appear in Apps & features on Windows 10, and on Programs and Features on Windows 7?

You can ignore the double entries. It is likely that you installed an early version of NBIA Data Retriever 2.0 or NBIA Data Retriever 1.0, both of which have different upgrade codes internally. The old software is removed when the new version is installed. If the newly installed app is not functioning as expected, you can manually remove the old app and reinstall the new app. However, it is not required to do so.

The NBIA Data Retriever always needs to run with a manifest file. Although the application can be invoked from command line, it works best in a desktop environment such as Gnome, KDE, and so on. Once the NBIA Data Retriever is installed in the desktop environment, you can click any manifest file with the extension .tcia to invoke the app.

Error invoking method or Failed to launch JVM

Using the NBIA Data Retriever, I get error messages for “Error invoking method” then “Failed to launch JVM”. How can I fix this problem?

These errors occur because the NBIA Data Retriever cannot work without with a manifest file. See Creating Manifest Files for instructions on how to create a manifest file using TCIA or an API. To avoid this error, download and install the NBIA Data Retriever first, then locate a manifest file on your computer. If you have not previously installed any versions of the Downloader App or TCIA Downloader, just click a manifest file and the NBIA Data Retriever will open it correctly. If you have installed the Downloader App or TCIA Downloader before, consider removing these applications first before installing the NBIA Data Retriever. This is not mandatory but will prevent you from having to specify which application your computer should use to open the manifest file. To do so, right-click the manifest file and choose to open it with the NBIA Data Retriever.
