IDE 1.6.8 (fresh download) on Windows7 stops after "Loading configuration"

Hello,

I made two different installations on two different machines runing Win7 of the IDE 1.6.8. On the first one, no problem. On the second one the installation process ended normally, but when I try to start the IDE the startup process terminates after the "loading configuration" without any error. Arduino_debug gives the following (known) message :

PS C:\Program Files (x86)\Arduino> ./arduino_debug.exe Loading configuration... com.sun.jna.platform.win32.Win32Exception: The system cannot find the file specified. at com.sun.jna.platform.win32.Advapi32Util.registryGetStringValue(Advapi32Util.java:552) at cc.arduino.os.windows.FolderFinderInWindowsRegistry.findInternal(FolderFinderInWindowsRegistry.java:53) at cc.arduino.os.windows.FolderFinder.find(FolderFinder.java:48) at cc.arduino.os.windows.FolderFinder.find(FolderFinder.java:58) at processing.app.windows.Platform.recoverSettingsFolderPath(Platform.java:56) at processing.app.windows.Platform.init(Platform.java:48) at processing.app.Base.guardedMain(Base.java:155) at processing.app.Base.main(Base.java:137)

The Arduino COM driver is installed successfully (I can connect Arduino using Putty). Windows version is 6.1.7600.16385.

Any suggestion appreciated Best regards UP

Try using the Windows Zip file for non admin install instead of the Windows installer: https://www.arduino.cc/download_handler.php?f=/arduino-1.6.8-windows.zip

If that doesn't work you can try using the Arduino IDE in portable mode by creating a folder named portable in the Arduino IDE installation folder.
