You may have so many custom brushes installed that WorldPainter runs out of memory.Try resetting the preferences by deleting the WorldPainter configuration file ( %APPDATA%\WorldPainter\config). It is possible you made some kind of modification to the preferences that cause it to no longer start, for instance setting the default size larger than you have memory for.It will allow WorldPainter to start and operate again, allowing you to undo the change you made, or confirm that the change was what caused the problem so you know to undo it. If you made a change (such as installing custom brushes or a plugin, or changing a preference) and now WorldPainter won't start or is not usable any more, try using WorldPainter Safe Mode.WorldPainter won't start or is not usable any more
Note that that won't work if the problem is using a custom theme on Windows though! You can find links to those on the same page where you downloaded the installer. If you continue to have problems installing WorldPainter using one of the installers, you can try one of the installerless archives.
Try temporarily disabling any firewalls or virus/malware scanners you may have installed, or other software which might be interfering with the download or installation process.Make sure you are using a complete and legal copy of Windows, not a "light" or "modded" version which may lack components that the installer, or WorldPainter itself, needs.If checking the "disable visual themes" option worked you will probably have to do it for the shortcut for WorldPainter proper after the installation as well. Try checking "Disable visual themes" on the Compatibility tab of the installer file's properties, or if that does not work either, resetting the Windows theme to the default altogether. It is possible that a custom Windows theme is triggering a bug in Java and preventing the installer from starting.
If you're not sure, try the 64-bit installer first, if that doesn't work, try the 32-bit installer. Make sure you're using the installer for the right word size (32 or 64 bit).If that doesn't fix the problem, check below: If you do, it is 64-bit Windows, if not, it is 32-bit Windows. How do I know if I have 32 or 64-bit Windows?Ĭheck if you have a Program Files (x86) directory (so with the (x86)). On 64-bit Windows, 32-bit Java is installed in Program Files (x86), and is the wrong version. You should always be using the version of Java installed in Program Files (not Program Files (x86)). You can download 64-bit Java here (pick the file ending in. On 64-bit Windows, you should be using the 64-bit version of WorldPainter (it should not have _32 in the file name of the installer), and the 64-bit version of Java. You can download 32-bit Java here (pick the file ending in -i586.exe). On 32-bit Windows you should be using the 32-bit version of WorldPainter (it should have _32 in the file name of the installer), and the 32-bit version of Java. "Could not find Java on your computer"/"The JVM (.) is damaged"Īssuming you have actually got Java installed, the problem is probably that it is the wrong word size (number of bits).
sudo R CMD javareconfĪfter which I was finally able to install both xlsx and rJava package.For generic, non operating system specific troubleshooting information, check the Troubleshooting page. To resolve I just used the command shown in the error. If in doubt, re-run "R CMD javareconf" as root. Make sure you have Java Development Kit installed and correctly registered in R.
After a lot of google searches and trial and errors did, finally this worked sudo apt-get install r-cran-rjavaĪfter this another error which I was stuck into was,Ĭonfigure: error: Cannot compile a simple JNI program. This was still giving me the same error installing Java.
sudo apt-get update sudo apt-get install default-jre sudo apt-get install default-jdk I thought, maybe Java isn’t install on my system.
While installing rJava it gave me an error now stating,ĮRROR: configuration failed for package ‘rJava’ * removing ‘/home/ronakshah/R/x86_64-pc-linux-gnu-library/3.2/rJava I was trying to install xlsx package in R when it gave me an error stating that Loading required package: rJavaĪnyways, as I also wanted to install rJava, I moved to install rJava package. Although, all the information is present in the internet but it is scattered and it took lot of time to gather all the information which is relevant to me. I am on Ubuntu 16.04, 64-bit system, so I thought let me document all the things which I have done. Recently, it took my lot of time in installation of the rJava package in R.
