UCCNC shuts down unexpectedly

[Kitwn]

Thanks A_Camera, I will look at the Windows repair tool from Microsoft.
i said 'it's a known cause' only because my searching suggested that there have been many instances of programs crashing in general due to problems with this file, not that it's known for UCCNC. The CNCdrive forum has only one reference to a crash due to that .dll file and it relates to using later versions of the software (1.2112 and 1.2113).
I think I have a clone HDD for this laptop from about 18 months ago but I will have to search for it (I've moved house since then!) which might be an interesting test. I certainly have a spare mechanical drive I can load a new installation of W10 onto. I'm not going to trash the current installation if I can avoid it.

How big is your current hard disk?.
If there is enough space you could create a new partition on it. Load a new os and uccnc on there. (This will basically make it dual boot so you can choose which os to boot to at the start). Test new setup out without wrecking the existing install. If it all works out then you can either:
Move all your docs etc over to new os partition and delete the old os partition when done. Or.
Use new os for machine until you find a fix for the existing os and then delete the newer one.

I still use xp for Mach via parallel and am in the process of putting uccnc on there. It's basic and not bloated to death like w10.
I'm also setting up win7 on a seperate partition with both programs.
I'll assess which is the better and go with it.
Not a fan of w10 update forcing regime, even if you get it disabled.
