Google Chrome Portable Error

Hello guys,

i have Google Chrome Portable (GoogleChromePortable_8.0.552.224) and i use it for helping a friend to get more hits on browser-game to get better ranked.
i have made a programm, which starts chrome portable and close it after about 10 seconds, then it comes a reconnect by my fritz.box and then it starts with chrome portable and so on. this process takes 30 minutes and it makes about 150 to 160 hits, so chrome portable is getting started and closed für so many times.

But now the problem, sometimes there comes an error:

"Google Chrome Portable appears to be running from a location that is read-only. Would you like to temporarily copy it to the local hard drive and run it from there?

Privacy Note: If you say Yes, your personal data within Google Chrome Portable will be temporarily copied to a local drive. Although this copy of you data will be deleted when you close Google Chrome Portable, it may be possible for someone else to access your data later."

If you klick "Yes" and/or "No", the error comes the next day again. By searching at google i found nothing with these error!
Does anyone has an idea?

Thanks a lot!

Hans
