I can’t even launch Unity it just says it stopped working. Is it because I didn’t uninstall previous Unity?
You can have multiple versions of Unity installed. In fact you should not overwrite or uninstall your release version of Unity to use the Preview.

But why can’t I run newer version?
Post your log (C:\Users\username\AppData\Local\Unity\Editor\Editor.log)
& check this thread just in case:

You are all using Windows 7, there must be something wrong 
Same bug, besides I don´t even get an error message,no logs, it just does not start. (tried 32 bit and 64 bit versions and running it as admin)
I am using Windows 10, normal build of Unity works without problems.
Same issue here; on Windows10 Unity doesn’t start, and the event log contains these entries for each attempt:
1.
Faulting application name: Unity.exe, version: 5.5.0.62432, time stamp: 0x574539f8
Faulting module name: Unity.exe, version: 5.5.0.62432, time stamp: 0x574539f8
Exception code: 0xc000001d
Fault offset: 0x0000000002219880
- (Long entry stating that windows can’t access a file and because of this it closed the application)
Error value: 00000000
Disk type: 0
When is the next preview due? maybe fix
Hold on, those are two different things. The next round of features will be 3-4 months away, but the team are planning to do multiple builds of the current group of features, as they incorporate your feedback and fix bugs. I don’t know the exact schedule but I believe the plan is that the wait for those builds is much shorter.

If it’s any help, the actual exception is Illegal Instruction at
0000000142219880 vmovaps xmm0,xmmword ptr [string “m_AutomaticTextureFormat”+3D0h (014235C760h)]
in Unity.exe!MyAlloc()
Same here. And no log file to speak of in C:\Users\Admin\AppData\Local\Unity\Editor
Neither 32 or 64-bit works. 5.3.5f1 works as usual though.
Still looking into this problem.
Found anything yet?
Not yet. We’re releasing Preview 2 soon and that might fix some of the problems faced.
In release 2 of problems with start and work in 5.5 alpha on Win7 has not arisen! For me the problem is solved!
Thanks!!
