I trying to set registry key using:

Set-RegistryKey -Key "HKEY_LOCAL_MACHINE\SOFTWARE\Classes\7-Zip.7z\DefaultIcon" -Name "(Default)" -Value "C:\Program Files\7-Zip\7z.dll,0" -Type String

but I got error:

Cannot process argument transformation parameter 'ContinueOnError'. Cannot convert value "System.string" to type "System.Boolen", parameters of this type only accept .....

Set-RegistryKey -Key "HKEY_LOCAL_MACHINE\SOFTWARE\" -Name "(Default)" -Value "" -Type String

working OK.

What is correst syntax of Value - "C:\Program Files\7-Zip\7z.dll,0"

Strange that argument transformation error is for ContinueOnError.

Does specifying single quote to specify string literal work?:
Set-RegistryKey -Key 'HKEY_LOCAL_MACHINE\SOFTWARE\Classes\7-Zip.7z\DefaultIcon' -Name '(Default)' -Value 'C:\Program Files\7-Zip\7z.dll,0' -Type String

No, I got different error:

Cannot process argument transformationon on parameter 'Type'. Cannot convert value "C:\Program" to type "Microsoft.Win32.RegistryValueKind" due to invalid enumeration values.

Can you try by not specifying the -Type parameter as the default type is already String?

or specify the Type parameter like so?:
Set-RegistryKey -Key 'HKEY_LOCAL_MACHINE\SOFTWARE\Classes\7-Zip.7z\DefaultIcon' -Name '(Default)' -Value 'C:\Program Files\7-Zip\7z.dll,0' -Type [Microsoft.Win32.RegistryValueKind]'String'

Sorry, I tested it again and your solution work for me.

Which solution worked?

Your first advice using ' instead ".


Thx again

Cool, yw. Using " instead of ' interchangeably works in most cases but strange bugs can crop up sometimes if not being careful because PowerShell will always scan text inside " quotes to see if they can be interpreted in any way. Using ' string literals where you know it's just text avoids such issues. In some cases, using the two interchangeably can also open you to security vulnerabilities when accepting input from some source for execution.
