I have the same issue, both on windows and mac.

here the same OSX and Windows with the latest version

I had a similar problem on my computer which could be solved by changing the administrator rights for the Fixture Builder.

Please try this:
- Right click on the desktop icon
- go to properties
- go to the tab compatibility
- activate the checkbox "run as administrator"
- restart the application and your computer

Please let me know if this works! If not please describe in detail how you can force this problem. I need as much details as possible to discuss this with the development.

Thanks,
Lars

Start the Tool wait until the Main window opens --> instant Crash

Did you try the procedure mentioned above?
Which version of windows so you use?
With Administrator rights?

As mentioned we need as much details as possible!

On MacOSX nothing works.
The error message:
An exception of class NilObjectException was not handled. The application must shut down.

Please double-check your version of the Fixture Builder. Not every Fixture Builder Version is suitable for every Windows/Mac Version!

Please use the v1.2.1.2 for the following operating systems:
Microsoft Windows® 8
Microsoft Windows® 8.1
Microsoft Windows® 10
Apple OS X 10.10.5 Yosemite

For older Windows versions please use v1.1.0.4!

Cheers,
Lars

I use the latest version of OS X : 10.11.5

The fixture builder 1.1.0.4 works fine
The new one doesn't work

I've never seen a new version that only works with older OS !

Hello,

I'have same problem with Window 10 Pro last update in administrator right

Hey everybody!

The developers had a deep look into this problem and found something. The unstable behaviour was caused by an compilation error. We are really sorry for that, but luckily we were able to fix this!
Within the next 24h you will find a new Fixture Builder version (1.2.1.3) on our website, please download this version and give it a try!

Sorry for all the inconveniences!
Lars

The new version works Thanks

Thanks @Maggi123

The website will be updated during the night, then the issue should be solved!
