Failed to install DevOps Test Runtime on Windows 11 25H2
When you attempt to install DevOps Test Runtime on Windows 11 version 25H2, the standard installation might fail with an error message.
The installer might display the following error message:
There is a problem with this Windows Installer package. A program required for this install to complete could not be run. Contact your support personnel or package vendor.
Resolution
To work around this issue, you must install the
devops-test-runtime.msi file by using a command prompt as
an administrator.
Note:
You must ensure that the file name of
the MSI package does not contain any spaces. For example, if you download the
file multiple times, your browser might save it as devops-test-runtime
(1).msi. Running the installation commands with spaces in the
file name causes the command to fail and triggers an error dialog. To avoid this
issue, you must rename the downloaded file to remove any spaces before you run
the commands.
Perform the following steps:
- Open a command prompt as an administrator.
- Navigate to the directory where the .msi file is available.
- Enter the following command in the command prompt:
The installation window with the progress bar is displayed.msiexec /i MSI_PATH - Click Proceed to accept the download of the
proprietary certificate if prompted.
You have installed DevOps Test Runtime by using the command-line interface.
