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.

Korg styles free download. 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

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.
