Registry - updating a string value

[pd123]

Hi,

I am having problems updating a value in the registry. I can open the subkey up, and read values no problem, but when I try a HKwf.SetValue("LastRun", "Yes") I get the following error message:

Cannot write to the registry key.

It doesn't seem to suggest a permissions problem, but does it need setting? The code is a vb.net exe, and is been started from the Administrator account.

Any suggestions welcomed.

Thanks,
pd123

Sorted it - forgot to set the "writable" boolean when calling OpenSubKey.

Doh!
