We experienced something similar on one of our test Macs where it wouldn't run the exact same application that all of the other Macs ran without issue, and for some reason these steps seemed to fix it:
1. Delete the iCamSource Pro from the Applications folder.
2. Download the iCamSource Pro dmg file from our site, open the dmg, and copy the iCamSource Pro.app to the Desktop instead of Applications.
3. Run the iCamSource Pro that is on the Desktop. (You will be prompted to confirm that you want to run an app that you downloaded from the Internet, but other than that it should launch as expected.)
4. Quit the iCamSource Pro, and move the app to the Applications folder.
5. Launch the iCamSource Pro from the Applications folder, which should now work without issue.
Hope that helps!
If you are still having problems, please let us know what the error message says and we can troubleshoot things further.
So my icam pro software told me of the update this morning, it downloaded and installed, but didn't relaunch.
I relaunched the software and I'm getting a, "This application "ICamSource Pro" can't be opened." error message.
I tried redownloading it directly from your page, and get the same problem. Any suggestions on what else I should try?
