What is happening?...Software, hardward, and system, are being used...One of these things is failing to do something the other wants done...is it software, hardware, driver, system?....
Proper installation of Sonar software, and others request to my knowledge = "turn off virus protection" if being used when doing so, so as to not corrupt the installation....MOSTLY the reasons for the misdirection of the thread to security software UAC being turned off...all of it might be extreme, but also might be a overlooked path to a corruption....remove Sonar software that may have been affected if it was installed while virus scanner were running....IF it was ....,uninstall, reinstall SONAR without virus protection or any other security protection programs running.....and see what happens.
Just a guess....this could also include Drivers and bug fixes...turning off the security protection when installing from known distributors...is usually safe enough....
So turn them all off...When installing ...Scan them first...if you need to...but turn them off when installing....MS essential, Defender, and or others...which I include UAC....SO it could be corruption of the software,...and it could be Buffers...could be a lot of things...Not saying no to anything...but I will not overlook anything until we have X info from the Joyof60
And so that is how it comes to this....without X it is a crap shoot.
Some call it brain storming....before the sun comes up.
Wink.
