Hi everyone,
I recently updated Lens desktop to Lens Setup 2025.4.92142-latest and since then I am not able to boot up the app with below error:
I am on my work laptop and have limited access so not sure why Lens is suddenly asking for registry editing.
Please help if there is a solution to this.
Hi @tmunkhb,
Thanks a lot for sharing this issue â and sorry youâre running into this! Thatâs definitely not a great experience, especially when you just want to get your work done.
From what we can see, Lens is trying to read a registry value (MachineGuid) during startup, but your system is blocking that due to restricted permissions. This is common in corporate or managed environments where registry access is limited by your IT policy.
Weâll review this behavior as a team to see if we can handle it more gracefully in the app going forward.
In the meantime, we recommend reaching out to your IT department and asking if they can allow read-only access to this registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid
Thanks again for your feedback â we really appreciate it, and weâll keep you posted on any updates!
The problem is not the registry key: It already has âread-onlyâ access for the user and âAll Application Packagesâ. The problem is non-admin users is getting âaccess deniedâ running reg.exe.
A temporary workaround is to ask your admin give you âreadâ access to the executable C:\WINDOWS\system32\reg.exe (reason why the Access Denied error).
A fix is to update LENS to use this PowerShell command to get the machine ID instead of using reg.exe
(gi HKLM:\software\Microsoft\Cryptography).GetValue(âMachineGuidâ)
Thank you very much for the detailed analysis and for sharing this workaround â we really appreciate your input!
Weâll evaluate integrating this method as a more robust solution going forward. Your suggestion is very helpful.
Thank you both for replying, as I was unable to get admin involved in this situation I simply downgraded to working version for now.
