Android Question Error running first program

I'm getting the following error

Error: could not open `C:\Program Files\Java\jdk1.7.0_40\jre\lib\amd64\jvm.cfg'

I assume something went wrong on the install, but where do I check.

I found this file in the jdk1.8.0_45 directory.

It seems I have several version of the SDK installed. Do i need to get rid of them and start again? Should I be using the ;latest version?

Regards

Thanks for that,

OK, I thought I'd download the latest version again, 1.8.0_45 but that does not have the javac.exe file in bin.

SO after copying across the .cfg file, I now get a different error;

The currency.data file resides in the latter directory but not in 1.7.0_40!

Do I just keep copying across files for the newer version to the older? I do not understand where the problem is coming from

I uninstalled all the SDK's and started again. It worked.

Thanks for you help
Pete
