Mach3 Windows 10 64bit 1803 Provisional Patch

Like many in the CNC community, we and our customers have been affected by the Windows 10 (64bit), version 1803 update issue that leaves the Mach3 application unable to completely load (after profile selection, the splash screen will render and then disappear as the application crashes).

We've investigated the cause and developed a provisional patch to the Mach3 (version 3.043.062) application binary that has demonstrated effectiveness in resolving the issue. We are working together with the Mach development team to further validate this patch as they work to deliver an official release in the near future.

In the interest of helping those who have already been affected and can't afford to wait, we've decided to make the provisional patch available as an interim solution while the official fix undergoes further due diligence.

Mach3 v.062 Provisional Patch > http://www.cncrouterparts.com/dl/mis...p001_patch.exe

Before applying the fix, please ensure;

1. Mach3 version 3.043.062 is installed. (.62 can be downloaded here)
2. You are running Windows 10 64bit 1803 build

Please note that this is not an official patch from Artsoft and we are making it available "as-is" until an official release addressing this issue becomes available.

Congratulations and thank you! Even if it is unofficial and "as-is" I'd be very happy to try if I would have the problems and would depend on Mach3. Even though Mach3 is obsolete, it is really not good that it suddenly stops working, though the W10 1803 version is not yet globally distributed, which is good. Maybe there will be an 1804 soon, if more than Mach3 is affected, which will fix the issue.

Nice work on this.
While I don't run a machine with this PC, not being able to run Mach3 made it hard to provide help to others.

Quick update; The lastest Mach3 download from Artsoft, v3.043.062, posted on their site contains the fix for Win 10 64bit 1803 (and beyond)! > http://www.machsupport.com/software/downloads-updates

Future Microsoft updates are very unlikely to address the root-cause, therefore either the patch or the updated Mach3 download is needed for builds including/beyond 1803.

Happy CNCing everyone!

That depends on what the root of the cause is. If it is caused by a bug in W10 then I am sure it will be addressed by MS, but if it is caused by Mach3 not following Windows standard or doing something that causes some issues, or has a bug then of course, MS will not bother. Never the less, it is very good that Artsoft and you acted very fast. It definitely results in many happy faces if Mach3 can be kept going for a while more even if it is obsolete, outdated and too old, it is still a very good and useful software.

Is it the version that just says 3.043?
It doesn't say whether it .062 or .066, which was the previous version posted.

Hi Gerry - Yes, the "Mach3Version3.043.exe" Mach3 installer file currently posted (contains v3.043.062 +" Win10 1803 patch") is the correct binary. If folks have already patched their Mach3 install, there is no need to re-download/install Mach3 again.

These 6 updates I found online to be the cause but I don't have any of them installed.
There must be more that I don't know of.
Any help would be appreciated.

I realize this thread is about the Windows 10 patch and I've applied that to one of my machines running Windows 10 and it worked (thanks to CNCRouterParts and Artisoft)
However, I also have a Windows 7 32-bit controller running Mach3 with the LPT driver. It recently got broken when I allowed a Windows7 update. I've uninstalled and downloaded the new Mach3 install multiple times without any success - Mach3 still crashes the PC right after the splash screen loads.
Has anyone found a fix for this setup?
I've decided it's time to move away from Mach3, so I've ordered a Centroid Acorn controller setup and a UCCNC Eth300-UB1 setup to replace them, but I'd like to keep the Windows7 rig running while I build up the control boxes.
Thanks for any help.

I think the only option with Windows 7 is to roll back the updates.
