Issue during launching the UiPath Studio application

Help Studio
1

Hello,

I am trying to install UiPath studio on Microsoft Windows Server 2012 Standard. I am able to install the UiPath studio, but while launching the application i am getting the following error, as a result UiPath does not launch.

Error:

Error: System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task System.IO.Pipes.NamedPipeClientStream.ConnectAsync(System.Threading.CancellationToken)'.
   at UiPath.CoreIpc.NamedPipe.NamedPipeClient`1.<ConnectToServerAsync>d__16.MoveNext()

Few details

  • OS → Microsoft Windows Server 2012 Standard

  • UiPath version → 2020.10.9

  • .Net Framework version → 4.6.1

As the error says it’s not able to find the method, but i have cross checked the necessary .Net Framework version is installed. I am not sure still why it would give method not found.

Hello @Srini84

I have already referred this link

My system configuration is:

  • 8 processors
  • 128 GB RAM
  • 64 bit OS
  • Have sufficient hard disk space

As mentioned in the link, following redistribution are also already installed

  • Microsoft Visual C++ 2015-2019 Redistributable (x64) - 14.27.29016
  • Microsoft Visual C++ 2015-2019 Redistributable (x86) - 14.27.29016

To my best understanding the software requirements should be satisfied, this is where i need help, even after requirements are satisfied still why it is giving the above error.
