Which is equivalent in processing power as my i5 at work (tested that by re-encoding the same video takes practically the same amount of time on both boxes). My home machine has Windows 10, 24GByte of RAM and a AMD 4.1GHz A10 (APU) processor. It extracts just fine, but when I try to start the AsciiDocFX editor, I get a warning message saying that AV software, firewall or heap memory problem prevents the JVM from starting.
Now I take that archive home to work on a big documentation project. No problem, it works as intended on machines with Windows 7 till Server 2019 and everything in between. Created an archive from it and distributed this on several workstations and servers (Intel and AMD).
Thought I tried that after seeing that Oracle database client software (for Windows) uses the same trick.
By doing this, AsciiDocFX can be used as a portable application without the need to have Java installed. It raises the allowed memory to 256 Megabyte. If your application does not run fine afterwards, try raising the memory to 512 or even 1024 Megabyte instead.Īt work computer (i5, 16GByte RAM) I added the JRE folder (1.8) of another system to the AsciiDocFX editor’s root folder. The setting is available right away, you do not need to restart the computer first.
You can alternatively open the control panel manual to go there if you prefer it that way. Tap on Windows-Pause to open the System Control Panel applet.Here is how that is done (demonstrated using Windows 7, may differ slightly on other versions of Windows): Now, to resolve the error message we need to increase the size that Java can use for memory. Check the InitialHeapSize and MaxHeapSize values here (displayed in Bytes). Getting a virtual machine error is a sign of insufficient admin rights or that Java needs a larger global maximum heap memory size.Java on Windows uses an initial size of 16 Megabyte and a maximum of 64 Megabyte. You can find that out by yourself by running the command java -XX:+PrintFlagsFinal -version on your machine. What is a virtual machine error in Java?.To fix the annoying Java virtual machine error, you may try to start in 64-bit mode or use the steps described in this detailed guide. How do you fix JVM could not be started?.
In plain language, JVM is a virtual machine that enables a computer to run Java programs. If you have any other questions or if you have advice for other users to try, don’t hesitate to leave a comment below. The main reason is that it needs admin access in order to function properly.
