Hello… a few years ago I posted a question on the forums here about how to run both Java and Vassal from a flashdrive on a computer that didn’t have Java installed. With help from various sources here, I got it working and used it since then without a hitch. It’s ideal for my work environment where I have some free time over the noon hour.
However, I recently got a new desktop computer for work, and Vassal no longer works.
Vassal and JRE6 are both installed on the flashdrive. I was using the VSQL mod with Vassal 3.1.20 (due to compatibility issues) and I have a modified .bat file directing Vassal to the JRE installed on the drive.
I keep getting the following message, which I’ve never seen before:
“This application requires a Java Runtime Environment 1.5.0”
After some Googling I’ve tried a few things (reinstalling Vassal, resinstalling the JRE, downgrading to 3.1.19, creating another .bat file) and nothing appears to circumvent this. Any thoughts?
Update… for a lark I tried using the .bat file with “Run as Administrator” (as I don’t have admin rights to the desktop I’m using, which makes things difficult) and whoosh, Vassal runs.
I have NO IDEA why this is the case, as I never had to use this method before - I simply double-clicked on the Vassal .exe file and it always ran fine.
FYI, the computer is running Windows 7 and the .bat file on my flashdrive contains the following:
REM Execute this file to launch VASSAL on Windows
set path=.;%1%\VassalUSB\jre6\bin
start javaw -client -cp lib/Vengine.jar VASSAL.launch.ModuleManager %*
If anyone wants to weigh in with their thoughts from a technical perspective, I’m all ears, seriously.

That’s not the batch file we distribute, but it ought to work for
launching from your thumb drive.

My guess is that VASSAL.exe isn’t working for you due to a PATH
problem. Open a terminal. (Run “cmd”.) What output do you get
when you run ‘java -version’? What ouptut do you get when you
run ‘echo %PATH%’?
BTW, you don’t need to use 3.1.20 for VSQL anymore; a version of VSQL
compatible with 3.2 has been out for some months now.
Hi… the batchfile is one I created based on a suggestion resulting from my original inquiry about this a few years ago. It seems to do the trick, yes.
I tried running the “java -version” command in a DOS prompt but it wouldn’t recognize it. For what it’s worth, the PATH command generates the following:
Not sure what any of that means or if it’s helpful to you… but VASSAL now works as long as I select the “run as administrator” option when opening the batch file, so overall I’m satisfied!

I just got the same problem when I start Vassal : “This application requires a Java Runtime Environment 1.5.0”
My computer is running Windows Vista (crappy OS)
I run the latest Vassal version : 3.2.8 and I have reinstalled it before posting.
here are java versions installed on my PC : 6-update 45, 7-update 6 which I have reinstalled too.
I try to install 7-update 45 but I failed …
I also try to run vassal as admin but it fails to lauch as well. here is my PATH run as admin too :
C:\Program Files\ATI Stream\bin\x86;C:\Program Files\NVIDIA Corporation\PhysX\Common;C:\Program Files\Common Files\Microsoft Shared\Windows Live;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\hp\bin\Python;C:\Program Files\Windows Live\Shared;C:\Windows\System32\WindowsPowerShell\v1.0;C:\Program Files\ATI Technologies\ATI.ACE\Core-Static;C:\Program Files\QuickTime\QTSystem;C:\Program Files\Satsuki Decoder Pack\Filtres
Thank you for some advices and please forgot some english mistakes because I’m french
I installed only one java version (I ran javara and ccleaner in order not to be polluted by older versions). Its the one installed with vassal : 1.6.0_45.
I checked whether Java works and I got the good message. But Vassal don’t run anyway
Next step I go to find Vassal’s errolog.
But I don’t find it : I don’t have a VASSAL folder in C:\Documents and Settings<username> (I’m on Vista)

You said in your initial message that you have both Java 6 and Java 7.
Is that not the case?

What happens when you try to run VASSAL from the command line using
VASSAL.bat?
