SETOOL2LITE issues

I'm currently trying to unlock my w580i and I tried to install the setool2lite v1.10 but when I open the .exe file it gives me this message:

C:\Users\Stephanie\AppData\Local\Temp\wz9d12\setoo l2lib_lt.dll (The operation completed successfully)

It wont open the program like how my V1.08 will open

I think you might need to download it again, and I thought 1.11 was the latest version?

yes, setool2lite v1.11 is the latest version.

Install it? I tought it was only an archive that you just needed to extract it. No installing...
And by the way, that isn't an error
