  1. Just fixed a vexing problem that caused Windows 10 File Explorer to crash without warning any time I tried to display a folder containing a .vlp file. In fact, any Windows application I used to try accessing a .vlp-containing folder would crash without warning. Various browsers, MS Outlook, and TreeSize Free were several that I tried.

Also, I cannot find this file for download, not even at the OPC Foundation website. Incidentally, I did not disable UAC when installing UniOPC, if that makes a difference. Any help is appreciated.
