When I try to install Virtual Router I receive the following error: "There is a problem with this Windows Installer package. a DLL required for this install to complete could not be run. Contact your support personnel or package vendor." I am running Windows 7 x64 Enterprise with SP1. My NIC is on the list of supported devices. I have .Net Framework 4 installed.

Hi,
I know it's been a long time since you wrote here but I'm new.
I had your problem. I solved it by granting Administrator permission to user over the "Temp" folder of my machine.
You should do it in this way:
1) Be sure you can see hidden folders;
2) Go to 'C:\Users\"my user"\AppData\Local" and right-click on "Temp"
3) Go to "Security" or something like this (I have it in Italian, don't know how it is in English)
4) "Advanced" -> "Change permission" -> "Add..."
5) Here you type the name of your account;
6) Press "Check name" and then "Ok"
7) Now you should see you account: tick all the clickable permission;
8) Apply and then close;
9) Now you should be able to install the program.
Hope this could be helpful for others,
Sincerely,
Giovanni
