When installing the latest update I get an error, when it is almost all the way through.

"Error copying file from packed archive"
"C:/Users/ktoole/Downloads/SenchaArchitect-2.2.exe to c:\Program Files(x86)/Sencha Architect/bin/ion.pak"

I get an option to Abort/Retry/Ignore. I have just chosen to Abort.
I then get the message:
"There has been an error."
"Unable to copy file"
"The application will exit now."

I have tried downloading three times now and I get the same result. Architect does appear to be working when I run it, but there is something wrong with the update.
