I've installed mesh a few times on my AT&T Fuze - using stock ROMs and custom ROMs with varying luck. What seems to be consistent is that if its installed before I install compact framework 3.5, it works. After I install CF 3.5, it throws horrible exception errors. Most newer WM6.1 ROMs are baked with CF3.5 on them and I was not able to get mesh to install on them. My most recent experience was flashing to the latest Fuze ROM and successfully installing mesh. I then installed CF 3.5 and it crashed horribly. I uninstalled CF and the app ran successfully (with a small config error message). Has anyone else seen this?
