Why do I get a 1603 error when I try to deploy Adobe Flash Player?

There is a very good chance that you are attempting to deploy a version of Flash Player (or any free Adobe product like Acrobat Reader, AIR, etc) that was not meant to be deployed. 

Adobe doesn't allow the download site to be posted on a publicly accessible site. In order for you to obtain the link to download a version of Adobe Flash Player that can be deployed please visit and submit the necessary form to Adobe. They are usually pretty good about responding quickly.

If you are attempting to deploy a valid, for distribution, version of Flash Player AND you get the 1603 error, chances are that your AntiVirus software is preventing the installation from taking place. Make sure that you have an AnitVirus exception for the following directories (based on your version of PDQ Deploy)

PDQ Deploy 1.5.x - %WINDIR%\PDQDeployRunner

PDQ Deploy 1.2.9.x - %WINDIR%\PDQDeploy

PDQ Deploy Pro 1.4.x  - %WINDIR%\PDQDeployPro

    We can't stress enough the importance of obtaining the versions of Flash Player that are meant for distribution. If your installer file of Flash is very small (the flash installers that can be deployed are ~ 8 - 11 MB) then you do not have a version that can be deployed.

    Don't forget the other possibility... If Firefox is open and displaying a flash plugin, the flash plugin will not install.  Same with IE and the activeX flash player.  I have found that to be the case more often than antivirus software interfering.  If it were AV, wouldn't ALL software deployments fail?

    Good point. When I deploy Flash (Plugin or ActiveX) I always have an Action to kill Firefox, Chrome and Internet Explorer before the deployment action fires off. Being able to specify multiple actions is a feature available in Pro mode of PDQ Deploy.

    Well, I try to take a lower profile with my users.  I don't want to close browsers that may be in use.  I just push the individual flash players again at random times during the day until they finally succeed.

    You're just nice, Dwreese. I'm the curmudgeonly old nerd who got too many toilet swirlies in High School and therefore takes out his vengeance on all of his co-workers.
