no main class
 

Just after the fresh installation Minion doesn't start and show error dialog with "no main class". Screenshots attached. Logs are not because C:\Users\Олег\.minion is abscent. Windows 7 64bit. Minion is 2.0.9a.

Did you install the last Java JRE ?

***

Which isnt specified in the minion's requierment but is about your error.

Yep, was installed oracle jre 8u5. But as I see Minion install and use own JRE. Well, I deinstall my jre and reinstall Minion, the same error.

What strange is

C:\Users\Олег>java -version
Error: could not open `C:\Windows\jre\lib\amd64\jvm.cfg'

and there is not amd64 dir, only i386.
but

c:\Windows\jre\bin>.\java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) Client VM (build 24.45-b08, mixed mode)

And I don't know what installed this old i386 jre on my notebook with amd64 in this strange location, because oracle java installed in c:\Program files.

I uninstall oracle java 8u5 and manually delete c:\Windows\jre, reinstall Minion. The same error "no main class". I install oracle jre 8u5, now it's work

C:\Users\Олег>java -version
java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

Ireinstalled Minion, the same error "no main class".

olleg, Minion runs on its own JVM (packaged with its own java in its install directory) and you don't need to even have java installed on your system. Minion does not have permission to even write to C:\Windows directory.

I assume you installed Minion in the default location which would be C:\Users\Олег\AppData\Local\Minion\ on your system
Currently Minion has problems with unicode characters in the install path on some windows systems and you have one in your user name.

So uninstall Minion and try installing it some where like C:\Minion where there isn't a unicode character.

Please let me know if this works for you. Thanks :)

*Also what language and version of windows are you using? We are trying to reproduce this issue and are having trouble. We know it happens though because a few others have reported it. They also reported changing the install location to a path with out unicode fixed it for them too.

Minion does not require the user to install java on their system. It runs a java virtual machine that the exe starts up.

The only prerequisites is the MS Visual C++ Redistributable 2010 which Minion now checks for at install.

Yep, you are right. I got admin priviledges and install Minion in C:\Program Files\Minion, now it's work.
