That worked!!! Control Panel runs and i'm able to update the Panel and a few Telerik Programs.
Unfortunately when trying to update "JustMock R3 2017" and "JustDecompile_2016_3_1003_0_Free", those are also requesting the MSI installation files (that appear to be missing from the same Installer/Downloads folder). It said it is sending out an error report, but might you also have those old version zipped MSI files as well?
Thanks for all the help again!
