JavaCard OS

I download JCKit JAVACOS_1.0.5.36 , and I have already installed successfully using default settings on win7.

I am trying to open JCIDE, but error occurred, but pyApdutool and the available demos (WalletDemo) just fine. Only JCIDE.exe refuses to open when I execute it.

Would you please let me know how I can fix this issue?

This is a bug in the old version. Please download the latest version of JCIDE.
The new version has already fixed this bug.
