I'm trying to open IE on the W10 Technical Preview Eval Copy, Build 9841 and get the message below:
Runtime Error!
Program: C:\Program Files(X86)\Internet Explorer\IEXPLORER.EXE
R6031
-Attempt to initialize the CRT more than once.
This indicates a bug in your application
I figured out that some trash programs loaded in the back ground, once deleted, it is working again.
