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: System.MissingMethodException: Method not found: 'System.Threading.Tasks.Task System.IO.Pipes.NamedPipeClientStream.ConnectAsync(System.Threading.CancellationToken)'.
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.

Please help. If you need any more information, please let me know.
Can you please check below documentation
Hope this may help you
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.
Okay, may I know which kind of setup you are using?
Is it msi receieved from UiPath?
UiPathStudio.msi downloaded from cloud.uipath.com login
could you please re install the studio.
and before re installing make sure to clear the below data.
I have already followed the same link and uninstalled and installed again more than 5 times as admin and also as non admin user. Still facing the same issue.
Able to resolve this issue by updating the .Net Framework version to 4.8
Thanks @Srini84 @THIRU_NANI for your help and support.
