Epson JavaPOS ADK安装-加载Java VM时发生Windows错误2

Question

I recently bought an Epson TM-T20II thermal receipt printer for a POS application I'm developing. Whenever I try to install the JavaPOS ADK from the Epson site (Or the included software cd, for that matter) I get Windows error 2 occured while loading the Java VM .

I tried following this answer but that leaves me with another error: ZeroGr2: Windows DLL failed to load

I am running Windows 10 Pro x64 and have installed the anniversary update.

Any help on resolving this error and getting the installation to complete would be very much appreciated.

Answer 1

To prevent the Windows error 2 code, start the .exe from the command prompt(as admin) and add a paramater LAX_VM, so something like

> Epson_JavaPOS_ADK_1141.exe LAX_VM "C:\\Java\\jre\\bin\\java.exe"

I think the second problem is because of an issue with the Java 8 64-bit JRE. I can reproduce that error with the 64-bit jre1.8.0_101 but using the 32-bit version works fine. I also tried it with a 64-bit JRE7 and that worked as well.

Edit: it seems you need to start the command prompt as admin as well.

Answer 2

When I tried to install the Epson JavaPOS ADK, I end up with the two same errors :

• Windows error 2 occured while loading the Java VM
• then ZeroGr2: Windows DLL failed to load

I manage to make it work by :

• Launching the installer with @TrollGate's LAX_VM parameter : ie : Epson_JavaPOS_ADK_1141.exe LAX_VM "C:\\Program Files (x86)\\Java\\jdk1.8.0_101\\bin\\java.exe" in a admin command terminal
• Using a 32 bits JVM : I used the 32 bits jdk1.8.0_101

I didn't need to launch the terminal as administrator to make it work, but the installation manual states that it should be run with administrator's privilege . I didn't need to change the compatibility settings of the installer either.
