Citrix question

I am trying to install Vantage 5.2 on our citrix server, and during the
install I am recieving a warning message that states "the installation has
detected hthat there exists a previous install of progress in the following
directory v: progress(this is where we have our vantage) the install can
only install additional products t5o above directory" but we don't even have
v: mapped on the citrix server. Why is it giving me this message and not
allowing me a successful install.

Any feedback would be helpful
