"The update application has been updated and must restart in order to continue" error message keeps appearing

Hi,

Since the last update a couple of weeks ago (that created many technical problems for me), I am getting a "The update application has been updated and must restart in order to continue" error message whenever I open Studio 2015, but when I click "OK" nothing happens... trying to manually turn Studio off and back on just results in the same message; restarting the entire computer does not change the situation; trying to manually update Studio with "search for updates", same result... It is like this last update completely messed up Studio's updating ability... and I didn't find any information about it in KB :-(

*This is after I downloaded and used the Studio-KB9268-6 package as recommended to me by a kind member as a solution to the original problem caused by the update...

It did fix the original problem, but the updating feature of Studio does not recover...

Some other member mentioned that the Studio-KB9268-6 package fixed this issue for her, but it does not fix it for me (even after several times)...



Any ideas?

Thanks in advance.
