Dear Stuart,
I'm sorry to hear that you are having trouble with Dataverse. We have built the tool to work in environments like yours so I'm surprised to hear that you are having trouble. In order to help you, I'm going to need a little more information.
First, could you please confirm which version of Dataverse you asked IT to install? An easy way to verify this is by copying and pasting the contents of "<Dataverse Install Directory>\lib\java\lae-release.properties" into your response. This is a text file you could open with Notepad. Most of the time, this file will be located at "C:\Program Files\Dataverse\lib\java\lae-release.properties", but I know that some IT installations can move things around. You could also e-mail it to me at help@lavastorm.com. Please include the URL of this page in your e-mail.
Second, could you provide me with some details around how the software was installed? Was the software installed using your account with elevated privileges, or was it installed by logging in as a different user? If you are unsure, you can check by opening Explorer, typing %LOCALAPPDATA% into the address bar--with the percent signs--and then pressing Enter. Once you press Enter, could you tell me if you see a folder named "Dataverse" in that directory?
Third, could you provide me with a little more detail about how the 'Start Dataverse' link is not working? When the product starts, what window are you seeing? Dataverse can sometimes take a little longer than expected to start up and so refreshing your browser a minute or two after clicking the 'Start Dataverse' link often fixes the problem.
Once I have a better sense of the problems you are facing, I can help answer your questions around IT's installation of the product.
Hope that helps,
Rocco
