I tried to update from MC 18 to MC 22 but it failed. The download came in, I double clicked to install it, but MC 22 does not open. MC 18 is still working. I also tried a restore, but with the same result. If I go to the download, and double click, I get a message asking if I want to allow the program to make changes, but when I click yes, I get a message indicating that the license was already accepted. It does not open an extract box.
Does anyone have a solution ?
