I want to install Powershell v2 on an XP SP3 machine. It has previously had
v1 installed, which was never properly uninstalled. I have tried all the
solutions I can find to remove the old version. All the PS files and folders
have been deleted. Any reference to Powershell in the registry has been
deleted, but on trying to install v2 I stll get the message to remove
previous versions first. I guess it's looking for a registry key or keys
which tells it that PS is installed, finds it/them and stops the install.
I've tried looking at a registry trace with RegMon filtered to misiexec, but
there are still hundreds of successful reads & queries. I have saved the
Neither $NtUninstallKB926139$ nor $NtUninstallKB926141$ is present and I
can't roll back nor can I install v1, for the same reason as above.
