A lot of times when you run into problems like this, reinstalling the app will then allow you to uninstall it.
Tried to uninstall Adobe reader as I have switched to Foxit reader. During the uninstall process I received the following message.
"The batch program could not be opened. Verify that it exists."
Checked on-line and found that I needed 'ADBERDR813_EN_US.MSI'.
Downloaded it and tried again. Same message appeared.
Any suggestions how to get rid of this Reader on my computer.
