During the installation of .NET Framework 4.6.2, I got an error:
.NET Framework installation failed: -2146762486. A certificate chain could not be built to a trusted root authority
A solution to the above-mentioned error is given at this MSDN Blog link, which says to do the following steps:
1. Download the certificate http://www.microsoft.com/pki/certs/MicRooCerAut2011_2011_03_22.crt locally (Example: C:\Temp)
2. You can use the certmgr.exe utility to add the certificate by using the command line. For more information, see the Certmgr.exe (Certificate Manager Tool) topic at MSDN.
3. Open an admin command prompt and run this command: certmgr.exe /add C:\Temp\MicRooCerAut2011_2011_03_22.cer /s /r localMachine root
4. Next, try installing the patch KB3135996 or KB3136000
MY QUESTION:
The installation of .NET framework 4.6.2 has to be done on several production systems so, are the above-mentioned steps standard? I mean, could it create problem to install the same certificate on several systems? When the systems will be connected to the internet at some point, could it create conflict?
PS: Solving this problem (managing certificates) by connecting the systems to the Internet is not an option for me since the whole process must be offline.
could it create problem to install the same certificate on several systems?
No, it will not be a problem even if the systems would be connected to the internet in the future.
When you connect the system to the internet and do the update it could download a pack of trusted certificates. These certificates will be added to the trusted root store. Existing ones will simply be IMO simply replaced.
