I've had 2017 C3D installed on my Windows 10 machine for about 2 months now with no issues. I came in to work this morning and AutoCAD crashes on me during AutoCAD Civil 3D General Discussion Civil 3D 2017 Crashes On Startup. AutoCAD 2018 licensing crash – another reason to avoid subscription By Steve Johnson 22 May 2017, 9:10 pm 22 May 2017 AutoCAD for Mac, Bug, Crash, Crock, Hotfix, Licensing, Patch, Rental, Subscription, Update.
How many times have you been working in AutoCAD®, and then suddenly it freezes on you? Panic sets in, as you try to remember the last time you saved… You wait… and wait… and… thankfully AutoCAD® un-freezes, this time…
But what actually is the cause of AutoCAD® freezing? It depends – there are many potential reasons for AutoCAD® freezing, but some can be avoided completely with a little understanding of what’s actually happening.
Selections
The first and most obvious reason for AutoCAD® freezing is when we do things to a very large selection. What can sometimes be unexpected is when AutoCAD® freezes when we have merely selected the objects without doing anything to them. This can sometimes leave us gazing at an hourglass thinking “I didn’t ask you to do anything! Why are you freezing on me!?”. Odd as this may seem, there is a reason for it.
When a selection is made, any on screen information that relates to your active selection needs to be updated; otherwise you’ll be working from incorrect information. So, if for example you have the properties window on your screen anywhere, even if it is docked with the auto-hide feature enabled, all the data in the properties window needs to be updated with correct information. The time that this takes is proportional with the amount of things selected, so you can see that simply selecting objects can be the cause of AutoCAD® freezing.
There are ways of working that allow us to drastically reduce the frequency of AutoCAD® freezing when working with a large selection. Make sure you select commands before you make a selection. This sends a clearer instruction to AutoCAD®, and it is dealt with more quickly than if we make the selection first. By selecting first you’re saying to AutoCAD® “Here are some entities that I am interested in – prepare them for me to use in any way”. This is vague, so AutoCAD® has to prepare for anything. However by invoking the command first and making a selection afterwards you’re saying “I only care about performing this action – these are the entities I want to perform it on”. This instruction is much clearer and skips out a lot that we’re not interested in. An extension of this is to get out of the habit of using the Delete key for erasing entities. Yes, it works. But again, picking the erase command first and then the entities sends a clearer message with a very noticeable difference in performance when working with large selections.
Commands
There are a few commands that more commonly cause AutoCAD® to freeze than others. Hatching is one of the main ones, but again, a little know-how can avoid this. A lot of people routinely use the pick-points option for defining a hatch boundary. I personally always try to draw in a way that makes hatching easy. For example, where possible I use closed polylines instead of lines. This allows me to then hatch later by selecting a boundary, eliminating the need to pick points, potentially making AutoCAD® hang. Take a look at my post on the RECTANG command to see what I mean.
When working in 3D, you might be tempted to avoid the 3DORBIT command completely in favour of the SHIFT+MOUSEWHEEL, but there is a reason you should generally use the 3DO command instead. AutoCAD® needs to prepare for 3D orbitting, and if you’re planning on manipulating the drawing a bit, you only want to make AutoCAD® hang for this preparation once. If you use the SHIFT+MOUSEWHEEL method, you’ll make AutoCAD® prepare for 3D orbitting each time you use it, which can be very time consuming on larger drawings. So for very small drawings, its fine to use SHIFT+MOUSEWHEEL, but for everything else use 3DO.

Networked Working
Working on drawings that are saved on some external network has been known to suffer performance issues. Try where possible to work locally, but only where doing so does not undermine whatever document management system you have in place (you do have a structured and coherent document management system. don’t you??).

When AutoCAD® Freezes or Hangs…
Wait!!! Do not mash the keys – however tempting that may be! Doing so will only make it take longer. Try to be patient. After a minute or so, you could try a few taps on the Escape key – sometimes you can cancel the command and regain control. After a few mins longer you may want to weigh up whether or not it is worth trying to regain control at all. Is the amount of work you have done since the last save worth rescuing? That will depend on how much work you did. Often, the bulk of the work is the thought processes that went into whatever you did in AutoCAD® – this work has still been done, and you can redo the actual AutoCAD® input quite quickly. If you choose to kill AutoCAD®, you might want to know this useful keyboard shortcut – Ctrl + Shift + Escape, which brings up the task manager.

Peachtree download 2018. Last week I find an issue on my customer’s computer. His AutoCAD 2013 always hangs on startup. It showed the splash screen but AutoCAD never starts. If there is a popup saying error message, it might be easier to fix.
So I did a little investigation to fix it. I tried to search on Google and found that it might be caused by several issues.
Here are a few that I found.
Check for LISP viruses
This is the problem that I found on his computer.The virus changed his acad2013.lsp, acaddoc.lsp and acadinfo.lsp. All those files are bloated to more than 300 MB! No wonder AutoCAD won’t start.
If you are not familiar with those files, acad.lsp, acad2013.lsp are functions that will be executed automatically when you start an AutoCAD session. acaddoc.lsp will be executed automatically when you create or open a drawing. In default installation, those files are only 1 KB in size. So if his LSP file is 300 MB, there must be something evil that cause that. You can imagine how long your computer will take to execute 300 MB routines!

Read more about VBA macro viruses and LISP based viruses in AutoCAD here. There are some suggestions there how you can prevent it from attacking your computer.
I’ve seen this kind of virus can mess your command, many things don’t work correctly. It even can send your documents through email client. But this is the first time I see it prevents AutoCAD from starting.

If you find this issue, the fix is easy. Just delete those files and replace with unaffected LSP from other computer.
InfoCenter process did not successfully closed in previous session
InfoCenter sometimes can cause problem too. There is a knowledge base that explain it’s because a background process did not end correctly.
However, WSCommCntr1.exe can also cause this problem when you first start AutoCAD. It’s a process that require internet connection. Some domain security, firewall or anti virus may have conflict with it.
When AutoCAD hangs on startup and force close this process will resolve the issue. You need to check your computer security settings if you want to use InfoCenter.
If you are concern because you work in secure location and don’t want to allow that process, you can disable InfoCenter as explained in this knowledge base.
Windows Update and drivers
AutoCAD relies on many prerequisites. Installing Windows update and updating your graphic card driver sometimes can resolve the issue.
However, I’ve experienced that my software won’t run after I installed Windows update. This forum thread is similar to my experience.
If this is the issue, Autodesk usually will release a hotfix or update for this issue. Check if any available on Autodesk support download page.
If you want to try uninstalling the update, you can open program and features then click view installed updates on the left sidebar.
AutoCAD installation is corrupt
The last thing that you might want to check is AutoCAD installation. In my experience, when AutoCAD installation is corrupt there will be warnings about missing files or wrong registry key. It won’t just hang or freeze during startup.
However, you can try to repair AutoCAD. And if it doesn’t work, the last thing you can do is to reinstall the product. I strongly suggest you to follow this clean installation procedure from this knowledge base.

Conclusion
Best Startups To Work For 2017
When AutoCAD failed to start, there are many things that can cause this. It can be viruses, Windows problem, hardware drivers, Windows settings (even Internet Explorer settings) and of course AutoCAD problem itself. It’s not easy to find what went wrong. I hope this will help you to solve it. Remember, this list is only for AutoCAD hangs on startup. Basically you will see no warning on your screen. If you see error warning, it usually has error code and finding solution might be easier.
Don’t rush it. Try to eliminate each problem to find what is wrong.
