The .NET fix worked well on my install, BTW.
Had the same problem on install except my server has no antivirus. But, I do have a Windows 7 Pro SP1 install with updates turned off YEARS ago.
Manually installed .NET 4.5.2 (https://www.microsoft.com/en-ca/downloa ... x?id=42642
), rebooted and myServer loaded - yah!
Dave, I want to thank you for posting the fix as more often than not...the problem is posted and a request for Teamviewer is made and that is that. Great to be have the fix available and fantastic then it works.
