Solved: System Manager 2.2 RC1 Error on Windows 8 - Page 2

Hi guys,

Just upgraded to System Manager 2.2 RC1 but keep getting an error when I try to run it.

Strange thing is I got this error with version 2.0.2 because I had installed Java 7. I resolved it then by removing java 7 and installing Java 6. However, version 2.2 requires Java 7 and wont install without it. I'm running Windows 7 Pro x64 w/ Java 7u17. I have both 32 & 64 bit Java installed.

Any ideas?

Success!!

Seems it is indeed a Java issue. Java 7 apparently brings support for IPv6, and to quote a user at the java.net forums:

"When you attempt to connect to an IPv4 address then under the covers it will use an IPv4-mapped IPv6 address."

The fix is to add an environment variable to force Java to use IPv4.

Environment variable "_JAVA_OPTIONS"

Value "-Djava.net.preferIPv4Stack=true"

Works perfectly now!
