I need to use some of the new functionality in the Dev build and just can not install it on our windows 7, 64 bit machines. It works fine on my personal windows 8 laptop but I can't get it to work at work. I have tried unistalling / reinstalling many times and Lisboa is fine but Dev won't work.

I tried the fix in Why is QGIS not launching? but no luck.

Problem signature:
  Problem Event Name:   APPCRASH
  Application Name: qgis.exe
  Application Version:  0.0.0.0
  Application Timestamp:    4fdce845

This is on multiple machines with Win 7 -64 bit.

I have been trying to install qgis-dev but I keep getting qgis_core.dll not found issues and I have looked online but can't find anything that works. You get the Dev screen (image) for a millisecond and then no output. The paths seem to load fine.

OSGEO4W home is C:\OSGeo4W

did you install with Admin rights? –  Nathan W Jun 16 '13 at 10:31
    
Yes I did try that as well. –  GeorgeC Jun 16 '13 at 11:00
    
That crash is for a different exe. qgis.exe is for 1.8. Is that the output you get? –  Nathan W Jun 16 '13 at 11:03
    
yes that was the output for Lisboa after I installed the Dev version. With the Dev version I get no output, the image with 1.9 Alpha comes up and you see "loading GUI" then it just stops processing. Can I share desktop with you? –  GeorgeC Jun 16 '13 at 11:36

This was caused by having a file named path.txt in the root C:\ making QGIS think it was running from the build directory. Deleting path.txt resolves the issue, I also changed the name of the file in bb8e47fc84d540f so that the chances of this happening again is reduced.
