Download Problem Upgrading To Version 17.01

I was advised as a new 17.01 version being available, but while downloading, I received an error message regarding opening the file Qt5core.dll. When I chose to ignore, I was presented with a series of error messages for other .dll files (eg. MultimediaOts widgets, etc) that could not be written to. After ignoring a total of nearly 20 .dll, I was able to download the software, but am wondering if the functionality of the software will be seriously compromised because of these missing .dll files.Please advise. Thanks for your help!

You should close Shotcut when installing a new version. It is also possible that Shotcut was closed but there was a background process that did not (shotcut.exe or qmelt.exe), which you can try to kill in Task Manager, or you might need to reboot.
