PROBLEM SUMMARY
When running a playbook on Windows and specifying CAPI as the installation, the certificate cannot be installed when run from Powershell( either 5.x or 7.x)
The same playbook run from the command prompt works as expected.
We utilize Powershell scripts to run our vcert playbooks.
STEPS TO REPRODUCE
Open Powershell pwsh
Issue the following command:
PS H:\vcerttesting\vcert.exe run -f .\CAPI_Playbook.yaml --debug
Playbook Yaml:
config:
connection:
platform: tpp
url: "https://mytppserver.com"
credentials:
accessToken: "*****************"
clientId: "myClientId"
certificateTasks:
-name: "CAPI Install"
renewBefore: 31d
setEnvVars: ["thumbprint"]
request:
csr: service
zone: "vcert\testing\my\space"
subject:
commonName: "myserver.example.com"
installations:
- format: CAPI
capiLocation: 'CueentUser\MY'
capiFriendlyName: "myserver.example.com"
capiIsNonExportable: True
EXPECTED RESULTS
I would have expected the operation to work when using PowerShell(pwsh) as it works with cmd(Command prompt)
I tried opening pwsh as an administrator and the same failure.
ACTUAL RESULTS
2026-04-29T13:23:07.032-500 ERROR vcert/playbook.go:151 error running task {"task": "CAPI Install", "error": "errot installing certificate at location CurrentUser\MY: failed to install certificate into CAPI,stdout: '': failed to run script function "install-cert": failed to run script file: Get-Item: Cannot find drive.

ENVIRONMENT DETAILS

COMMENTS/WORKAROUNDS
No workarounds at the moment as I cannot run ps1 scripts from PowerShell
