Never try a used PC

I was given an used PC as a newcomer to my company. Well, I should say,
everything was fine even though I want to reinstall it but I don't have
time.

And now, a client told me to export to PDF rather than Word, fine, I rushed
to code and testing. But Acrobat Reader always prompted certain file didn't
even exist, what's more, this mentioned name is not the same name I tracked
in Visual Studio IDE. I didn't realize it was an environmental issue and
tried harder and harder to fix it which no need to say failed ulitimately.

I tried the same web application on another clean machine and it worked
like an charm.
