I....and some others... have experienced an issue when trying to run CCP that generates an error message about AgileDotNet that says "The secured image was created usig a trial version of AgileDotNet and can not run on this machine." and when you click on the OK button it just exits to desktop.
Someone on the VRS Forum discovered that he could get past the error by changing his computers date to sometime prior to January 1, 2021 but this can have a negative effect on your system, especially if it is on a domain network.
I found a workaround solution with a freeware utility called "Time-Stopper" from apponic.com.
The utility basically tricks other programs into thinking the date is different from the actual computer systems date. The nice thing about it is that it does not affect your systems date and time settings or affect any other programs other than the ones you specify.
To use it (run it as admin) for CCP, you select the .exe file of the CCP version you want to use. Set the date you want the program to think it is whenever it is run. Create a name for the new short-cut that will be created for it and click the Exit button. It's recommended that you then delete the old shortcuts. When you want to run CCP you just click on the new shortcut you created and it should open up normally.
I DON'T ENDORSE THIS PROGRAM OR THE COMPANY THAT PRODUCES IT. IT'S FREE AND SEEMS TO WORK OK FOR ME....BUT IT MIGHT NOT WORK OK FOR YOU, SO USE AT YOUR OWN RISK.
