Client installs but won't launch

I am working over TeamViewer with a remote salesman on his new laptop, fresh out of the box from Dell. I have applied all windows updates and installed .NET. I am able to launch the Epicor installer, no errors. It installs ok. I see the config files there that point to our app server. But when I launch the client, nothing happens. It appears that epicor.exe closes in less than a second, with no error. It is nowhere to be found in task manager. I deleted the client and reinstalled a 2nd time. Same thing. I have not seen this before. Any ideas? Client is 10.2.300.15

Well the fix was just copying the full client folders from a known good system to this system. I have no idea what was wrong though.

I have run into this same problem and have never found a fix. One time I wiped the PC and it worked, but I just copy the full client folders like you mentioned.

If you copy a zip\folder from the web, windows will block the DLLs. Not sure if this was the case for you, but something to be aware of. You can unblock them manually (for a gazillion DLLs) or use a script in powershell to unblock an entire folder.

Wow, I did not know that Chris. Thank you

Sure thing, if you ever run into this, here is the ps command to use:

Get-ChildItem -Path ‘C:\Epicor\YourFolder’ -Recurse | Unblock-File
