With the release of exMon 4.5, package parameters have been changed in a way that can affect executions. With the release exMon no longer adds single quotation marks around package parameters and instead user must specify whether they want single or double quotation marks themselves as such:
{@myParameter[default:1]} should become {@myParameter[default:1][quotes:']}

If you are upgrading exMon and were directed to this page you are using package parameters and so these instructions are very important for you.

1. Copy and paste the package id’s you get when upgrading to notepad. The ids should be listed below the link that sent you here.

2. Resume and finish upgrading exMon.

3. Open exMon administrator and using the package ids open each package and make sure it runs properly.
