Install fails - generic 1603 MSI error

I am attempting to perform a silent install by calling the workfusionrpaexpress.msi directly. The install “works” but the msi log comes back with a generic 1603 error. The desktop icon is there and I can run it but I’d like to see if I can have the install work without the error. I checked in the msi log file and the following is the only entry I could find that could be related to the final 1603 error. Any thoughts? I’ve tried installing with anti-virus disabled.

Hi Jeff, do you get this error in RPA Express 1.2.0?

I will have to download that version and install it. Other info about my issue, I have tired it on windows 7 SP1 and windows 10 build 1607. When I try and run the RPA recorder I get a popup about java runtime environment must be available in order to run Recorder. No java virtual machine was found.

I downloaded version 1.2.0 and I see the resources folder now has 6 MSI files. Do you have silent install instructions, are there command line switches I can use with the rpaexpressinstaller.exe?

Hi Jeff,
No, sorry, we don’t have instructions or best practices for silent install as it is not formally supported in RPA Express. It wasn’t tested so we cannot guarantee that silent install will work correctly.
