can't install 1.6.8 on Windows 10 laptop

Using Arduino IDE 1.x
1

I have just tried to install 1.6.8 (.exe version) on my windows 10 laptop which had been successfully running an earlier version of arduino. The old version was successfully uninstalled but when the new version tried to install I got an error message saying that various files could not be written to. Can anyone help me to install the new version? Thanks

What files? When you have a technical problem always post the full text of any and all error messages

The message that I get is:

Error opening file for writing:
c:\program files (x86)\Arduino\java\bin\awt.dll
Click abort to stop the installation
Retry to try again or
Ignore to skip this file.

When I press Retry I get the same message.
When I press Ignore I can proceed but have the same message for the following files:

fontmanager.dll
java.dll
javaw.exe
net.dll
nio.dll
verify.dll
zip.dll
jvm.dll

Thanks

Is there a reason why you want to go from a previous version to a new one? If not, don't upgrade for the sake of upgrade; newer is not always better.

Exit the other program that is using the Java runtime.

Thanks both. If I can't find what else is running Java I'll certainly revert to the old version (I just assumed that the newer version would be better).

I restarted the laptop and managed to install Arduino 1.6.8. But when I try to run it I get the Arduino startup window, which says "configuring" and then "initialising packages" and then nothing happens. Looking in task manager, Arduino is not running.
Any ideas? thanks

Which version of the Arduino IDE were you using previously?

The version that used to run was 1.0.6.

I have un-installed and immediately re-installed 1.6.8 which now appears to be working. I don't understand but it seems to be fixed. Guess I'll not really know until I've uploaded some code.
