Some 3rd party software may cause crashes in Carlson+IntelliCAD. The reason is improper intrusion into OpenGL video service or Windows shell extensions. Following software is well-known to cause this:
* Raptr In-Game Overlay
* Nahimic Audio
* A-Volute
* AMD Gaming Evolved
* PlaysTV
* GeForce Experience Share (it can be disabled)
* Asus Sonic Studio
* Dell Backup and Recovery
* Trimble (Advanced Process Designs) TCC Explorer
* Trend Micro OfficeScan (it can be disabled)
* Google Drive shell extension
* EgisTec (egis) security solutions
* Bitdefender anti-virus ("Total Security" or "Antivirus Free")
* QNAP Qsync
* Dell AlienRespawn
* FileCenter from Lucion Technologies

Unconfirmed but plausible:
* Adobe Creative Cloud
* HP ProtectTools (Security Manager and Sure Click)
* Waves MaxxAudio (Pro)
* Other game overlays and messengers

Actually not all versions of these applications causes issues; in most cases these bugs are fixed in the most recent version. So to avoid such crashes you need to update mentioned software or delete it.

Another reason of crash may be an error in one of Microsoft libraries (clr.dll). Unfortunately we have no control on it. We introduced an option for more aggressive error detection.

One more reason of crashes may be unsupported graphics hardware & software, such as:
