I get the following error when I attempt to install you MSI file to C:\Program Files\ThumbsPlus9 (this folder contains a registered copy of v9 SP1 build 3938):
"An installation package for the product ThumbsPlus cannot be found. Try again using a valid copy of the installation package 'thumbsplus9sp1setup.msi'."
I can't find this file on my C: drive or on your website, and there's only one reference to it in your support forums which suggests uninstalling/reinstalling. My problem with this is that there's no entry to ThumbsPlus in the Windows "Uninstall or change a program", nor is there an uninstaller program in the ThumbsPlus directory.
Thank you for a prompt reply.
Best,
John
