I launch fan.exe and nothing happens. Altrough in XP fan.exe writes in console.

I add to fan.exe in properties: "launch from administrator" and "compatibility with XP 3". But this not help.

What wrong?

Did you add it to your Path variable? I'm running Win7 and I got no such problems.

You can see how to turn on debug in Setup chapter

If you can't get it to work, then you can just use Java command line too - see here

I used launcher debug:

1st try:

c:\Programs\Fantom\bin>fan
-- launcher version 1.0.50 2-Feb-10
--   args[0] = "fan"
-- init
--   fanHome = c:\Programs\Fantom
--   config.props:
--     runtime=java
--     java.options=-Xmx512M
--     runtime.substitutes=/E:/fan/src/buildall.fan           = E:\rel  /E:/fan/
src/buildboot.fan          = E:\rel  /E:/fan/src/sys/build.fan          = E:\rel
  /E:/fan/src/sys/java/build.fan     = E:\rel  /E:/fan/src/sys/js/build.fan
  = E:\rel  /E:/fan/src/sys/dotnet/build.fan   = E:\rel  /E:/fan/src/compiler/bu
ild.fan     = E:\rel  /E:/fan/src/compilerJava/build.fan = E:\rel  /E:/fan/src/b
uild/build.fan        = E:\rel
-- parseArgs
--   fanArgs (0)
-- getRuntime = java
-- findJvmPath
ERROR: Cannot read registry: SOFTWARE\JavaSoft\Java Runtime Environment CurrentV
ersion

2nd try with path to jdk:

c:\Programs\Fantom\bin>fan

--   args[0] = "fan"
-- init
--   fanHome = c:\Programs\Fantom

-- loadJava
--   load c:\Program Files\Java\jdk1.6.0_26\jre\bin\server\jvm.dll...
ERROR: Cannot load library: c:\Program Files\Java\jdk1.6.0_26\jre\bin\server\jvm

3rd try with path to jre:

c:\Programs\Fantom\bin>fan
-- launcher version 1.0.50 2-Feb-10
--   args[0] = "fan"
-- init
--   fanHome = c:\Programs\Fantom
--   config.props:
--     runtime=java
--     java.jvm=c:\Program Files\Java\jre6\bin\server\jvm.dll
--     java.options=-Xmx512M
--     runtime.substitutes=/E:/fan/src/buildall.fan           = E:\rel  /E:/fan/
src/buildboot.fan          = E:\rel  /E:/fan/src/sys/build.fan          = E:\rel
  /E:/fan/src/sys/java/build.fan     = E:\rel  /E:/fan/src/sys/js/build.fan
  = E:\rel  /E:/fan/src/sys/dotnet/build.fan   = E:\rel  /E:/fan/src/compiler/bu
ild.fan     = E:\rel  /E:/fan/src/compilerJava/build.fan = E:\rel  /E:/fan/src/b
uild/build.fan        = E:\rel
-- parseArgs
--   fanArgs (0)
-- getRuntime = java
-- findJvmPath
--   java.jvm = c:\Program Files\Java\jre6\bin\server\jvm.dll
-- initOptions
--   options:
--     -Djava.class.path=c:\Programs\Fantom\lib\java\sys.jar
--     -Dfan.home=c:\Programs\Fantom
--     -Xmx512M
-- loadJava
--   load c:\Program Files\Java\jre6\bin\server\jvm.dll...
ERROR: Cannot load library: c:\Program Files\Java\jre6\bin\server\jvm.dll

But via java it works:

c:\Programs\Fantom\bin>java -cp %fan_home%\lib\java\sys.jar fanx.tools.Fan -vers

I never have problems with launch on XP.

The launcher programs are 32-bit, you might want to check that your installed Java is not 64-bit

If using 64 bit Java on a 64 bit Windoze machine you can delete / rename bin/fan.exe and create the following bin/fan.cmd:

@java -cp %fan_home%\lib\java\sys.jar fanx.tools.Fan %*

which allows you to run .fan scripts and Fantom main methods. e.g.

fan build.fan
fan afGundam
fan afGundam::Main
