When I double click sdk-installer, an exception 'Could not access key 'occured.
Asked by Ronaldo Huang:

My system is windows 64.  
I have downloaded sdk-installer-8.2.6.exe from [https://marketplace.atlassian.com/apps/1210950/atlassian-plugin-sdk-windows?hosting=server\&tab=overview](https://marketplace.atlassian.com/apps/1210950/atlassian-plugin-sdk-windows?hosting=server&tab=overview "https://marketplace.atlassian.com/apps/1210950/atlassian-plugin-sdk-windows?hosting=server&tab=overview"). But when I double click the exe file, an error following occured:

Exception:
