This came in from Kevin who was having problems with deploying any software via PDQ Deploy. It turns out that his company's antivirus software was deleting the temporary install directory that PDQ Deploy uses during a deployment.
"I think I might have resolved this on my own. We use Vipre enterprise edition for antivirus software. I did not realize that PDQDeploy creates a temporary install directory with C:\WIndows. I think the antivirus software's real time scan catches the folder creation and then deletes the contents before the installation can finish. I added a exception rule to the antivirus policy and so far so good. Thanks. Kevin"
