Opening the menu Tools > Options in Milestone Management Server crashes

After opening the application Management Server, I go to the Menu Tools, I select the entry Options, but the Options does not load.

Instead, a window opens and I can only click on the button to close it; but no options window pops up.

When I close that window, another one pops up:

Then, the application is frozen and a new pop up shows, describing an exception error:

Do you have any idea about what can be happening, plesae?

Thank you very much and have a nice day.

OK…

Solved it…

I found this information in this link:

https://developer.milestonesys.com/s/question/0D50O000054fdc6SAA/client-error-from-my-first-dll-default-guid-has-not-been-replaced

I overwrote the IDs of the interfaces as it is explained there:

I sought with CTRL + SHIFT + F in Visual Studio for the string “internal static Guid”

and I changed the numbers so they would be different

(For one of the test PlugIns I am using, I added 1 to each value; and for the other I added 2 to each value)

I compiled the PlugIns, copied the *.DLL files in their respective folders of the PlugIns

Then I was able to open the Menu “Tools > Options”
