Power Shell Pro Installation issue with VS 2019 Professional

Issue Synopsis:
trying to install power shell tool pro extension with Visual Studio 2019 Professional, it shows the installation of extension is successful but when we try to figure out an extension in VS, it’s not reflecting in list of Installed extensions
The main errors reflecting in log file are:

1.The extension is signed with an invalid timestamp.
2.Capping recursion at 5 directories in each extension root due to ‘default limit’.
3.The extension with the ID PowerShellTools.VS2017 will not be installed for Visual Studio Professional 2019.
4.Invalid certificate: PowerShellTools.5.9.8.vsix

Can you upload the full log or send it to me at support@ironmansoftware.com

I just tested this myself and do not see the error related to signature.

6/21/2021 7:44:46 AM - Signature Details...
6/21/2021 7:44:46 AM - 	Extension is signed with a valid signature.

Are you working on an internet connected machine?

Hi Adam,

Can you assist with the issue, please?

Hey @Amna,

Can you email support@ironmansoftware.com? If you did and didn’t get a response, it may be because you attached a PS1 file and the virus scanner blocked the email. Try renaming your script to .txt and send again.

I have the same problem absolutely. But VS 2019 version is Enterprise.
The computer is not connected to the Internet.
Do you have a solution to this problem?
