On my office computer a Mac mini 2009 I have Autocad LT 2017 Mac running without issues for a couple of weeks.

On my home laptop Macbook pro 2009 Autocad LT 2017 runs for a couple of days and than out of nothing I get the folowing error on startup:

"Exception in AcExperience.bundle ARX command"

Both systems run on Mac OS X el Captina 10.11.6

The first time I did get this error I couldn't really find a solution online,

So I did an un-install by the app, and a reinstall the problem still was there. Afther that I tried a un-install and manualy trow away all tempory files in the "aplication support" location for 2017. But i'm not planing to do this every other day on my Macbook pro.

I did some minor modifications on the toolbars: less buttons for almost every bar on de left side. and made my own bar for the measurement tools

I only get the option to click OK on the message's and than Autocad doesn't respond anymore.

Is there anybody with the same problem and/or a solution?

EDIT:

I found a solution to get Autocad LT 2017 Mac working without a reinstall:

You need to delete the following folders In the appliction support -> Autodesk folder:

"2017" in "ACDLTM"

"2017" in "ADUT"

"AutoCAD LT 2017" in "Web Services"

Don't know if deleting one of these would do the trick as well but it works without a reinstall now. (still curious what makes autocad give this error.)
