atf_converter.exe not doing its job.

Hi, the following is a copy/paste from a thread I opened over at the VRay forums:

Hi,

We got a rather serious problem here. Recently the ATF for importing STEP/IGES data kind of messed itself up?
When I tried on my personal computer at home, the (at 26MB relatively lightweight data) imported in about 30 seconds. Here at Work on two seperate PCs running the same Max version I left it running for the whole night and the ATF importer was just stuck at 8% CPU, same amount of RAM, etc. doing nothing.

It seems to have degraded over a period of weeks from firstly taking a longer time then usual, then only working after a max or PC restart, to now not working at all.

Do any of you have similar experiences and/or a fix? I'd like to avoid reinstalling max for pipeline reasons.

--------------------

I already tried resetting the user settings (as in rename the ENU folder) and tried importing with AntiVirus and Firewall software turned off. Attached a DxDiag file if it helps.

Software:

3ds Max 2016 (18.0 SP4)

Windows 7 Ultimate (6.1.7601 Service Pack 1 Build 7601)

I have no idea what would cause this, the importer .exe is the right one, sha256-signed by AD, so I can rule out a tampered importer application.

Hello @Anonymous,

Thank you very much for posting this.  I will admit I wouldn't have guessed that the MCG folder was the culprit.  I am going to create a new tracker issue with this and your graciously attached .rar file.  Again, thank you very much for the update and information.  

Best Regards,

Semi-bad News. While on the PC I didn't reinstall Max at this fix worked, on the other one it didn't.

The one where I reinstalled max and discovered the fix, it worked until I reset the PC via image restore from two weeks ago. When I then tried to apply the same fix, it didn't work anymore.

I am tired of it though, so one PC works with said fix so it's fine for me at this moment.

Hello @Anonymous,

I'm sorry to hear that.  I have logged this into the tracker to be investigated with a link to this thread and I attached your .rar file to the case.  QA will look into it and when I know more I will update the thread.  Thank you for all the information you have already provided, it is very helpful.  I have added your new information to the case as well.  

Best Regards,
