Failure to add license key on Windows Vista or higher
product: Bricscad & Architecturals
version: All
last reviewed: 2010-05-19
Symptoms
Though the user is logged in as administrator, the license manager still doesn't accept a valid license key, with one of the messages below:
- "Failed to add license key (error 25)" (or error 27).
- "Error creating registry key (need administrator rights for this operation)."
- "Error opening registry key."
- "Error setting registry key value (need administrator rights for this operation)."
Cause
On Windows Vista or higher, access rights are more restricted. Even if you are logged in as administrator, it appears that the application has not enough rights to write in the registry under HKEY_CLASSES_ROOT.
Resolution
Log in as a user with administrator rights, and launch the application by right-clicking the shortcut, and choosing "Run as administrator".
More information
(Windows Vista only):
To avoid having to choose "Run as administrator", you can turn off "User account control". See Control Panel > User accounts and family safety > User accounts > Turn User Account Control On or Off.
