I seem to be getting update errors. Why do these automatic updates keep failing?

Automatic updates can fail due to a several reasons, but the problems are generally related to a combination of anti-virus software, firewall settings, or a combination of the two. When you launch Virtual CRASH, your machine will send a request over the internet to find out if an update is available. If there is an available update, you will see the following:

When you select "Yes," zip files associated with the update are downloaded from the internet, then unpacked and installed in your Virtual CRASH installation area. Anti-virus software and firewall settings can prevent some of these steps from being correctly executed.  We recommend, if possible, to place Virtual CRASH on your anti-virus software's list of unrestricted applications. If this doesn't work, the most aggressive approach may be to temporarily disable your anti-virus software during the update process, then resume your normal anti-virus and firewall settings after completion. In the case of Norton anti-virus for example, turning off the features shown below, then selecting "Yes" on the Virtual CRASH update prompt, will typically guarantee that the updates will be properly installed.

After the updates install, simply switch these features back on. 

WebException Error

In some rare instances, users have reported seeing the following notification:

This error indicates a communication problem between the user's network and the Virtual CRASH servers. One possible solution to this error is to allow Windows to perform any needed Windows updates, reboot, and try launching Virtual CRASH again. Again, ensure all firewall and anti-virus software are disabled during the update process. If this does not solve the problem perform the manual update process described below.

Manual Update

In the event that automatic update continues to fail, follow the process below (written in the context of Virtual CRASH 3). Note, the same process is applicable for both Virtual CRASH 3 and Virtual CRASH 4:

  • First, completely uninstall Virtual CRASH 3, and delete the installation directory C:\Program Files (x86)\vizi\Virtual CRASH 3
  • Then delete the directory: C:\Users\(user)\AppData\Local\VirtualStore\Program Files (x86)\vizi\Virtual CRASH 3
  • Go to, download the trial version of Virtual CRASH 3, and run the installation application. 
  • Once installed, launch Virtual CRASH 3, press "No" when prompted to perform an automatic update - you will perform the update manually.  
  • Download an update installation application directly from our European partner site:
  • Simply follow the instructions on the site shown below to execute the manual update:

Launch the application once the download completes.

The update process should then complete automatically. 

The video below shows the manual update process:
