Apparently, the file is corrupted. The install gets so far, then gives errors about its inability to copy files fro the corrupted install file. Arg.
 
I downloaded these in IExplorer 8 - was this a mistake?
 
Ideas?
 
 

Yes. Use Firefox.

I find chrome is flawless,but I suppose Firefox must be ok,I uninstalled I.E.,after 5 months,soo slow,and so much junk on the page,kind of like a talk show,with terrible guests,and their all talking rubbish...........hmmm.......I need sleep!

Goodnight Happy X2 er's!

Yes - it appears to have been the browser - I am confirming the solution for anyone else who needs to know this: don't use IE 8.x to downloadthe files.

X2 is now installed.

I used chrome and when I double clicked to open part 1 exe I got an error message that says package integrity check failed: the package has been truncated or corrupted, and will close . Please try to obtain a valid copy. I am going to try to download part 1 again. Hopefully, I won't get this error again.

So far, the process has been fine for me. It's ironic that Firefox works well for the download - but sucks for this forum.

Ok, reloaded part 1 realized that it was user error. If you read it says turn off your antivirus. I wanted to just get into it and skipped the reading part. I figured I read everybody else's issues and could just bypass that part. 

I was wrong and by the way this is the best sonar ever! The sound is incredible!
