Hi chaps, I have a piece of software that I'm trying to deploy via GP, something I've done several times, the deploying works but the registry key that I have manually entered in to the MSI via Orca is not working, I admit to having no knowledge of MSI's so this may be a really obvious problem to fix. The reason I am editing this MSI is because the program was never meant to be deployed according to the software manufacturer, they won't provide any support either as the person/team that created the program and MSI have left! I have to install it on 90 PC's so installation on every machine is not an option. I have also tried manually entering the missing key to the registry after installation but the program then complains that it has been tampered with. The key entered is under the Registry settings, LINGO, the string that you see in that field has been taken from a known working installation and the string translates as "server1" On a standalone installation you do get the option to enter the server name and it works, maybe there is a section in the MSI so I can just add that server name in instead of the reg key idea I have been trying??? If any could take a look at the MSI or suggest any other way around this then it would be much appreciated Thanks Hope this all makes sense!!
