 The installation program hangs during upgrade, what can I do? Export knowledge base Export     SubscribeSubscribe      Show article info

If you have problems when upgrading to a new version of the system and the installation GUI just hangs when upgrading, then this is probably due to the fact that you are using an old Java version. 

 

Try to run the installer from a console with the command: java.exe -jar VisionProject-XX.X.X-installer.jar (In windows run Start --> Command prompt to execute this)

 

If you get any problems in the console, such as the ones below, then install the latest version of Java 7 and try again by using the latest Java explicitly with the command below:

 

"C:\Program Files\Java\jdk1.7.0_79\bin\java.exe" -jar VisionProject-XX.X.X-installer.jar
