PDF Creator 0.9.9 Installation Failure

Installation results in my antivirus (Vipre) blocking:

Program:
is-OOQ18.tmp
(Rogue Security Program)
...a known bad file was blocked from opening

Also...

C:\\Program Files\\PDF Creator\\PDFCreator\\unins000.exe

An error occurred while trying to rename a file in the destination directory:

MoveFile failed: code 5

Access is denied.

Click Retry to try again, Ignore to skip this file (not recommended), or Abort to cancel installation.

I have tried re-installing three times and have downloaded the installation file twice as well.
