[This is a duplicate of BUG 58154 - mod JTH]
I installed a new setup for v15 and this is the error I'm getting at startup and the app then closes.
Exception EGestureException in module PortableAppsPlatform.exe at 0024EEEA.
Unable to enable or disable IRealTimeStylus: The parameter is incorrect.
Please supply your os version. Bit depth. Language. Full install path. And whether you have a touch screen or stylus pad.
Sometimes, the impossible can become possible, if you're awesome!
OS: Win7 x64 on an HP850G3.
Bit Depth? True Color 32bit.
Full Install Path: C:\Test
Looks like 15.0.1 fixed this issue. Thanks!
