I found the error code on the Internet and downloaded the installation files to my hard drive and also could not install the application...received same error message. Asked our software admin if he would check the files...he said he experienced no problems installing the software.
Also I read this discussion:
Exit Code 20 primarily signifies required files are missing in the installer, this could be due to a bad copy operation. I recommend you please copy/download and unzip the installer again to your local machine and then trigger installation. That should work fine.
Sorry...but this solution did not work for me...unless I am doing something wrong...please advise.
Exit Code: 20 - install source path does not exist Install source files are missing. Reextract or copy the contents of the installer.
Someone else at my office was able to install and uninstall on their machine.
Are they using the same installer that you're using to install/ uninstall?
Are you trying to install from an installation disc or from a local file copy?
