Error trying to run Chairgun on new computer

[wahoowad]

I wanted to validate some older range cards I made so downloaded the latest version of Chairgun to my new PC. It is running Windows 10 and I notice the Hawke website doesn't list Windows 10 as supported (uh oh?).

So I run it, and get the following error "No JVM could be found on your system. Please define EXE4J_JAVA_HOME to point to an installed 32-bit JDK/JRE"

I download/install the latest JRE from Oracle and see it added itself to the PATH statement. Chairgun still won't run and throws the same error.

I add an environment variable of EXE4J_JAVA_HOME and point it to the JRE install location of C:\Program Files\Java\jre1.8.0_121\bin  but I keep getting the error. Anybody know why?

I'm on Windows 10 using v4.3.1 with no issues. I think I had to update Java, which you've done so not sure.

I also run Win 10 with no problems. Try the old "uninstall/reinstall" trick. Mine did the same when I installed it on Win 7. I had to uninstall, then, after updating Java, I reinstalled. That fixed it.

Well...sorry to trouble you as I figured it out. Chairgun doesn't seem to have been updated in quite a few years and wants to older 32-bit version of JRE, not the 64 bit which I had originally installed. I went ahead and installed the 32 bit and it started working.

Probably you're getting the error where it can't find the java JRE.

Check that you have java installed.

Then create a chairgun.bat file with the following contents adjusted to your directories:

SET EXE4J_JAVA_HOME "C:\Program Files (x86)\Java\jre1.8.0_201\bin"
"C:\Program Files (x86)\ChairGun4\ChairGun4.exe"

(x86) is the 32-bit version of Java chairgun wants.
