After starting AC 20 CPU is on 100%

[Anonymous]

After i start my ArchiCAD 20 CPU rises to 100% with 2 processes called cURL Executable which link to Archicad somehow. After stopping that both of them ArchiCAD works just fine but it is really annoying to do it every day. Can someone please help? I work on ThinkPad Yoga 260 Win10 x64. I tried to just wait but after 2 hours nothing special happend.
Thanks for advice.

I do not have those processes running. I would say it is related to other software.

After i right-click that process and click properties location path is the path to archicad

If it is being used by ArchiCAD20 it is only when starting the program and it is closed so fast I don't see it pop up on the process manager.

Maybe contact your local reseller for support.

Hi Guys,
We have one of the guys in our office who regularly has an issue with this. (once or twice a week)
He had 18 versions of cURL.exe running under the same instance of AC22.
I tried to replicate this issue with the same job and Task Manager open to see what happened;
1. Opened AC22 and cURL.exe opened momentarily and then closed itself as part of the start-up process.
2. I opened the nominated job and all was well.
3. I opened a 3D view and cURL.exe started and stayed open.
4. I opened another instance of AC22 and as before cURL.exe opened momentarily and then closed itself as part of the start-up process.
5. I opened another job and nothing happened
6. I opened a 3D view and nothing happened
7. I went back to the first job and killed cURL.exe and it did not re-start.
8. I opened 3D view and nothing happened.
Not sure if this enlightens anybody, but am keen to find some sort of resolution.

Hello All,

Actually, the curl.exe is used in several applications to communicate with services over the internet. In ARCHICAD it is used for the same thing: License Manager communication, BIMx Transfer Site communication, communicating with BIMcomponents, usage logging (if you opted in), etc. (so it is used at several points, not just at startup).

At startup, if ARCHICAD tries to communicate with certain services, but something won't let the cURL.exe connect to the internet, the cURL.exe keeps trying to connect until it succeeds, which never happens, thus the startup process gets stuck.

This is usually caused by an Anti-Virus Application or a strict Firewall/Proxy setting, that stops the cURL.exe from communicating with the services over the network. In both cases put the cURL.exe and the sites it tries to reach on the exceptions list / white list, and open ports 80 and 443 for it (it communicates through those ports - http protocol over TLS/SSL).

What happens to DJ Design's colleague though is something a bit different, I think. As far as I understand for him the cURL.exe doesn't get stuck at startup, but during normal work. This is actually caused by the same thing (and the solution is the same), but in this case whenever you do something that would need to communicate through the cURL.exe (eg. searching in the Object tool tries to connect to BIMcomponents), it is blocked, and won't close until it manages to connect. As this keeps happening more and more instances get stuck, and in the end it can hog the resources of the computer (slowing it down).

If you are not sure what might block cURL.exe, keep turning off background applications, and see which might make a difference, and try to connect to the internet from different networks. If you can't find the cause yourself, after an incident like this, gather the Fastlogger files from the computer, and send them to your local support team for them to analyze.

Thanks so much Daniel, I suspected it was something along those lines. We will investigate and report back when we have a resolution so that we may help others.
