Installation Stops (Hangs) During Download - AVG anti-virus blocks installation or update of Voyant

Description: Installation hangs midway and will not continue. 

Answer: Are you running AVG anti-virus software on your computer?

Unfortunately, AVG has introduced a bug in their latest release that treats all Java downloads (not only Voyant) as potentially malicious and blocks them. They have stated that this will be fixed in their next release, but until that happens, AVG will need to be disabled entirely, at least temporarily, to complete the download. Once downloaded, you should be able to run Voyant without issues. However, subsequent updates of the software, when they are released periodically, may require AVG to be disabled again to allow their installation to his computer.

The component with this bug is called Resident Shield. Sometimes disabling only the Resident Shield is enough to allow the download; however, I've found that this isn't foolproof whereas disabling AVG entirely, installing the software, and then re-enabling it is.

Note that until AVG addresses this, you might have to temporarily disable their software in the future when we release updates, in order to allow updates to be installed to your computer. I'm not certain this will be the case, but if AVG is blocking all Java downloads it will probably block our updates as well. Updates are released on an ad hoc basis but we usually do one to two production builds a month, which are normally released over the weekend or events (BST).

The AVG software protects your computer on multiple levels. In case you need to disable all AVG components at once please follow the steps below:

1. Open the AVG Program.

2. On the Tools menu, click Advanced settings.

3. Click Temporarily disable AVG protection in the menu on the left side.

4. Select the Temporarily disable AVG protection check box, and then click OK.

5. Choose how long you want the protection to be disabled and whether to disable the Firewall as well, and then click Disable real-time protection.
