Unity Startup Crash problem fix-
Check your graphic card is up-to date , may be its the problem of graphic card.
If your graphic card is not up-to date update it.
If iT doesn't solve your problem.
Check if there is any problem with your directx.
to check the directx
Press WINDOWS+R and type dxdiag and hit enter.
if there is no pop up about error and you can see your directx version there then your directx is god to go but if you get an error regarding DIRECTSHOW the it is the problems of codec and if you cant see any version of directx there then you need to install directx in your pc.
to solve the problem of DIRECTSHOW download the Codectweak tool to fix codec causing this problem.
and to install directx just download the directx from the official microsoft website and install.
if your unity still crashes at startup then it is the problem of some conflicting applications you have installed on your pc. Basically it is by the adblocker and malwares from LAVASOFT which are hard to detect by any anti-malware programs so you have to delete them manually.
To do this go to your control panel and search for any
Lavasoft application and uninstall them.
then go to the C:/Windows/System32 and find LavasoftTcpServices32.dll and another file under it named with Lavasoft you cant delete them if you try , so to do this run your command prompt with admin permissions and type following command
netsh winsock reset
It will ask you to resatart your computer and if not just restart your computer, now you can easily delete those files.
jus go to the C:/windows/system32 and delete LavasoftTcpServices.dll and another lavasoft file under it.
Sometimes these Lavasoft dll files are also found in SysWOW64 , so it will be good to cross check C:/windows/sysWOW64 for any lavasoft dll and if you find any delete them and you are done here.
Try to open your unity now , hope it will not crash this time.
If your unity is still Crashing just go to the crash report file and send it to us we will help you.
You will find your unity crash file at
C:\Users\HEWLETT PACKARD\AppData\Local\CrashDumps

THANK YOU!!! I've been trying without success to install and run Unity for ages on high end laptop that was less than a year old, and it was so frustrating. I tried every suggestion I found to no avail, but this is the only site that suggested the Lavasoft fix, and that finally did it. Thank you so much!
ReplyDeletethanks if you have any other problems regarding unity or any other tool let us know.
DeleteThank you so much I was so desperate to get unity working
ReplyDeleteI fixed my problem after lots of tries (installing new version of Unity, renaming working project, disabling Graphic driver, uninstalling newly installed programs,...).
ReplyDeleteMy solution: Uninstalling a software for Graphical Fonts (which wasn't directly related to Unity) fixed my problem right away.

ReplyDeleteThanks!!! It is working!
ReplyDeletei didnt have a crash report and anything else didnt work :(
ReplyDeleteGreat contribution. Thank you for sharing!!
ReplyDeleteTHANK YOU VERY MUCH
ReplyDeleteLavasoft was the problem - I had to uninstall "Web Companion" and then Unity 5.6 opened. Hallejuah! Thank you kind sir!
ReplyDeleteThank you very much. I always get this problem. This solution always works.
ReplyDeleteI wish i got an error message, 5.6 just hangs after the splash screen.
ReplyDeleteUsed to work with 5.3 or 5.2, thats the worst part.
I tried the CodecTweak Tool and it didn't do anything to help the DirectShow problem. I also downloaded the newest DirectX (DirectX 12), and found no LavaSoft applications on my computer. Unity still crashes. Any suggestions?
ReplyDeleteThank you
ReplyDeleteI had the "Lavasoft" Problem and now unity works perfecly
I don't even know where I got this "Lavasoft WebCompanion" but hey I followed your instructions and it worked, thanks dude.
