I just tried getting it installed with no luck either. Our IT department directed me to an Apple site (https://discussions.apple.com/thread/7767240) with instructions using Terminal, but that didn't work. Why is there no support page about this issue with a definitive answer?
Is there anyone who has successfully installed this on Catalina?
Can we get an updated installer please?
Found a solution folks:
I figured some things out after diving into the installer script, the way it works, and what it’s attempting to do. Once I realized some things I figured out a way to bypass the script. Here are written instructions below. It may seem like a lot, but if you focus on what’s in bold, it’s not so bad.
For what it's worth I just attempted and was successful in installing and launching PTG Standalone on macOS 10.15.6. I tried on both PS SIS 18.104.22.168 and 22.214.171.124.
What is your current value for "Allow apps to be downloaded from:" on System Preferences -> Security & Privacy -> General. If its App Store only then that could be the issue.
While the Standalone App is ideal the JNLP should also work as long as you have Java 8 installed.
I originally followed those same steps, but ran into several problems before finding my own way. Here's what my experiences were:
Changing my security settings in System Preferences was the easiest part since it's not from the App store. Even after doing that it ran into problems as described above.
The JNLP version is specific to PTG, That is the "Older Launch" link after clicking the drop down. It's listed under the Installer link.
I am not following you. Could you elaborate on what is JNLP? On my screen it says PTG 2.8. I have never uses the "Older Launch" link. Only the one shown as a button in the image. Everything seems straightforward like it should work, but it hasn't for myself and others. It's posted on Apple communities as well.
JNLP stands for Java Network Launch Protocol, which is how PTG was originally designed to operate, like ReportWorks. Specifically is uses the Java version the user installed on the client. The Standalone App, aka the Launch button, was added to bundle a known working Java version that was separate from what the end user may have installed. There was also concerns at the time that JNLP would be removed from support by Oracle and Apple but that never happened (or at least has not happened to date) and why a separate installer was built.
So long story short that "Older Launch" should also work if you have Java 8 already installed on you Mac.
I can't speak to why you're seeing issues on your Mac though. Digging in to the installer from what I can tell everything is signed correctly based on Apple's codesign tool.
Ok, thank you. I figure it was something related to Java. I don't know where to go from here. The process of installing has not gone smoothly at all for myself and other Mac users where I work. The only way I got it to work was to realize that the installer kept running into errors moving the app so I just bypassed the installer and moved it myself. The launcher still doesn't work at all either. When I click Launch it just downloads the launcher each time. Now I just click the Gradebook app and sometimes it seems to launch a second instance of itself (on the dock), but it's working. It's not ideal, but it seems that installing has been a longstanding issue for many Mac users.
Thanks for your insight.
