I have CIS 5.4 running XP Pro SP3
The ‘remove’ option is not present in ‘Add or Remove Programs’
Revo can’t uninstall either, stating ‘The installed product does not match the installation source(s). Until a matching source is provided or the installed product and source are synchronized, this action can not be performed.’ ‘Contact your administrator or product vendor for assistance. If there is a matching installation source, type it below or click Browse to locate it.’
The default source is "C:\Documents and Settings\All Users\Application Data\Comodo\Installer" and the file being looked for is “CIS_Setup.msi”
