System Explorer should be installed in c:\program files\system explorer or c:\program files(x86)\system explorer directory. in this directory make file start.bat, type there systemexplorer.exe /NOSERVICE , save file and try to start it.

Try to start SystemExplorer.exe /NOSERVICE

Should be fixed in next release. Thank you

Shutdown System Explorer. Open c:\programdata\SystemExplorer\config.ini and set menuwidth to higher value. Open System Explorer.
