run-time engine problem in Labview 2009 and Labview 2010

[lenienter]

I have a problem with Labview 2009 and Labview 2010. I updated my Labview 2009 into 2010. But it turned out to be a trial one, because i did not have the serial number. So I uninstalled the Labview 2010. however, the funny stuff came over. I cannot use my Labview 2009. So i uninstalled Labview 2009 again. But eventually, I could not reinstall Labview 2009. Every time i had a runtime error and i could not proceed with the installation. in addition, any installation  related to Labview is not permitted and the same error came up every time. it is very annoying.

So, What is the deal?

I attached the error here. Any comments or advice are welcomed and appreciated.

By chance is this machine's language set to any non-English locale?  You would check the locale setting by:

Opening Control Panel.
Opening "Regional and Language Options".
Looking Under "Regional Options" >> "Standards and Formats"

If it is set to something besides English, trying setting it to English and please report back what locale it was set to (or if this even solves the problem).
