@biggreenterp Thanks for reporting this, and welcome to the Microsoft Edge Insider's community!

We have a bug open for a known issue with downloading MS Edge from Safari, specifically. Can you please try removing the previous download and trying it from another browser and/or trying one of the Insider builds. Please let us know if neither of those does the trick, and we'd be happy to troubleshoot further.

I have the exact same issue. Except I downloaded my installer from Google Chrome. @Deleted 

[#4]

Just tried with Safari and same issue. Guess Edge is not ready for macOS yet.

[#5]

@biggreenterp@steve8141 This error has nothing to do with edge per se. It is an issue that was introduced in macOS 10.15.4. Here is how I was able to fix the error. When you launch edge (in this case) - it will not start and thrown an exception window with error details. Do not close that window. Now immediately launch Edge again - it should start normally. After that you can close the exception error details window. This step will also permanently fix the problem - say you quit Edge and open it - it should open it correctly for you. 

As I mentioned earlier, this is a problem not just with edge but other new apps especially 3rd party apps as there is some bug in macOS to validate the code signature - in some ways it is good that macOS is ensuring that software is not a hack or illegal download. Hope this helps.

Dear @ItsRoundRock 

Thanks a lot; that did the trick in my case: now I can use MS Edge without a problem. I wasn't expecting at all such a simple step to fix this problem.

[#7]

Glad it helped.

[#8]

@ItsRoundRock Tried this solution but edge still fails to start. My approach is alway to reinstall an older version of edge before i am able to use the browser. Is there any other solution out there 

[#9]

@Bishopgee1 Sorry that you are facing this issue. Do you see an exception? if it is related to code signature, then the solution I provided couple of years back could help. However if it is some other exception, then I would not know. That said, I know Edge browser has been updated may times - maybe a specific version could be causing since you mentioned an older version is not causing the issue. If you could report the error, that could help as well.
