Hi Ben, can you add some more details so we can try to reproduce:

- what Windows version are you using?
- which installer do you use (osgeo4w or the NSIS)?
- did you ever run one of the nightlies (that is: do you have a 'profile' already)
- if so can you remove the 'profiles' folder? (On Windows10 it something like: C:\Users\<YOU>\AppData\Roaming\QGIS\QGIS3\profiles)
- try on another machine if possible
- try another installer (like osgeo4w for example)

With me (I'm using the Osgeo4W installer on Win10-64) I've always installed all 3.x versions without problems.

Thanks for following up.

- I'm using 64 bit Windows 7 Professional Service Pack 1.
- I use the stand alone installer.
- I tried to load a nightly somewhere along the way, but didn't get very far. I thought something like this might be the case because when I first installed 3.0.0, I was prompted whether or not I wanted to import settings from QGIS 2. I said yes, but I haven't seen that screen with 3.0.1 or 3.0.2.
- I removed the profiles folder. I should note that after I did this, I once again got the option of whether or not to import settings when opening for the first time.
- I was able to install and run 3.0.2 on 64 bit Windows 10 with no problem.
- I tried the osgeo4w installer but got the same crash screen.

Is this a Windows 7 compatibility issue? I tried the install on a machine that is identical to mine except it has never had any version of QGIS 3 loaded. It crashed the same as mine did. Here is the log:

Mmm, I do not have Windows 7 machine anymore...

Are you able to try on another Win7 machine?
Or a clean one?

If not: I would try (as shown here: https://qgis.org/en/site/getinvolved/development/bugreporting.html#log-output-on-windows)
- remove the full osgeo4w install directory
- then do a fresh osgeo4w64 install of ONLY qgis-dev (which holds debug symbols)
- install Debugview

If debugview is active, and start that dev version of QGIS you should get more descriptive error messages

I posted a message to ask if other on Win7-64 have problems:
https://lists.osgeo.org/pipermail/qgis-developer/2018-May/053199.html

I have QGIS 3.0.2 (OSGeo4W64) running on a Windows 7 machine without a problem.

Hi,

We run QGIS 3.0.2 (OSGeo4W64) or standalone just fine on Windows 7, Service Pack 1.

Andreas

Are there any virus scanners active?

Sometimes, Anti-Virus software is screwing up other software.

Also, some plugins can make QGIS crash.

Just some ideas - but I am also in the dark, why it crashes for you.
