While installing ACT! 6.0 you receive a message saying :
Microsoft Internet Explorer version 5.50 or later is not detected on
your system
ACT! 6.0 requires Internet Explorer 5.50 or later to operate.
If you do not want to upgrade to Internet Explorer 5.50 or later, you may change the registry settings to make ACT! "think" that 5.50 is installed.
First, for safety, backup up your current Windows Registry
Also, contact your System Administrator or ask for assistance if in doubt.
