Hello Sir and friends,

Thank you sharing all the 3 tools for Unisoc. I downloaded and run R24 of all the 3 tools but got error missing some files .dll
But R23 run fine for me. Is there anything I can do to fix these error of missing some files .dll?

I've installed MS Visual C++ 2005 2008 2010 2012 2013 2015. Not sure which ones that I missed.

I wonder what's the difference between Update Tool, Research Tool and Factory Tool, but in the Tutorial section of their webpage, all the text is identical for the 3 tools, they only change the pictures. Anyone know something about this?

One thing more... Update Tool is on version 25.20 (it's still not listed here, but available on their site). The other 2 tools are on version 24.0. Version 25 size is about 9MB, version 24 size is about 6MB. That could be the reason behind the problems stated some posts above (missing DLLs).

In my PC, version 24 works, but i have a VC Redist AiO pack installed to avoid those kind of problems.
