Good afternoon,

I would like how I could run simultaneously on the same LEAP computer version 2018 and version 2012. A friend can work with both versions. I need to verify the compatibility of a file that does not give me the same results after updating.

Thanks in advance for the support.

There have been many changes to LEAP since the 2012 version, including bug fixes, which may be why the results are slightly different. We also do not provide technical support for previous versions of LEAP, but if you are having problems with the latest version of LEAP, please provide a detailed description of the problem you are experiencing and a copy of your .LEAP file to leap@sei.org, and we'd be happy to look into it.

Thanks,

Emily
