Wanted to install demo server for 10.0.0 version i downloaded osX version dmg and demo server from product support site but it says version doesn't match:
The selected file does not contain the correct version information for this version of DevTest Solutions. Please download the DevTestDemoServer.zip file listed for DevTest Solutions 10.0.0.431 JBoss Server with Examples
DevTest 10.0.0 OSX
Verified the DevTestDemoServer.zip is version 10.0.0.431.
We were able to just copy the DevTestDemoServer folder under the DEVTEST_HOME folder and then rename the folder to DemoServer.
You would do this anyway if you had to install the DemoServer after installing DevTest with a DemoServer since it not required to install the product.
