MC error on startup

[Thad]

Just this morning, I get this error every time I start a session of MC X9. I click OK and everything seems to work fine. When running 2017, MC crashes on launch and won't even run.

This morning when I logged into my computer, there was a notice that WIndows installed updates. That's the only thing that jumps out at me.

 

 

[gcode]

check and see if Windows update installed video drivers

If so, uninstall them and reinstall your old drivers

[Thad]

No video drivers.

yes.. my Win7 machine at work just finished an update

after I rebooted I'm getting the exact same thing

[gcode]

I sent a report to QC, I'll report back when I get a reply

One of our guys just got the same thing on his update. It is .NET update that has hosed Mastercam.

Roll back this update and hide it in win updates so it wont keep bugging you to install it.

 

I am sure it will get patched sometime in the future.

Its the tool manager trying to open on startup. If you try to open it that pops up, at least that's what I have noticed starting happening yesterday after the windows update

I try to edit a post with code expert using this win update.....code expert crashes a mile long error and Mastercam crashes on startup for me.

 

it could be the antivirus you are using that controls the severity of the incompatibility with Mastercam.

Google the update and you will see it is a patch for a vulnerability in the Net software.

 

 I rolled back the update and all is well...

How did you roll it back? When I click the link to show installed updates (where the option exists to uninstall an update), I don't see it in the list.

control panel/programs and features/   toggle view installed updates//////right click on the very last one...it is the january patch...one malicious tool remove andd the fram net fix....uninstall that one.

[gcode]

QC reports that a reseller has reported this issue and they are looking into it

In the mean time the safe thing to do is DO NOT install today's .NET Framework update

I think Microsoft knows something is up...

I checked my updates on my home system this am...I see the .NET update but note that it was unchecked by default....

[?Mark]

It bit me too this morning.

Uninstalling this fixed it:

 

 

Thanks Murlin!

I saw that at home too, before running into this issue at work. There were two .NET updates and I just assumed (yeah, I know...) that one was required before the other which is why one was checked by default and one wasn't. Anyway, I haven't noticed any issues at home, though I don't run MC at home.

I came in this morning and Windows Update had installed more updates last night. It was the .NET update that I hid back when I uninstalled them. I thought hiding an update put it on the "don't install" list. Anyway, the error with X9 is now gone and 2017 will now open, so something got fixed somewhere.

Now, .pdf files are associated with Chrome. Should (<--key word) be easy enough to fix, but just thought that was kinda odd. Not only do I not normally open .pdfs with Chrome, Chrome is not even my default browser. :headscratch:

Thanks Thad Windows downloaded the new patch on my machine too and I came here to see if anyone had installed it yet.

 

I don't let Windows install updates automatically so the patch is in the Que....

 

I will install and see what happens....

 

here goes nuttin... 

 

 

EDIT:    yes this patch works now.

Thanks guys!

This thread sent me down the correct path. I couldn't find the security update cited by previous posters but I did get it handled.

MY FIX:

Install "Microsoft .NET Framework 4.7.1"

Microsoft .NET Framework 4.7.1 (Offline Installer)
