For a non-Administrator's installation, the account you are logged
on as must belong to Power® Users
group.
Some information about DB2 Connect™ that must appear in the registry must be entered in the
HKEY_CURRENT_USER folder in the registry. Although many items will
be stored under the HKEY_LOCAL_MACHINE folder in the registry for
non-Administrator installations of DB2 Connect, the environment settings
must be changed in HKEY_CURRENT_USER.
A
member of the Windows Administrators
group must configure the Windows elevated
privileges settings to allow a non-Administrator user account to perform
an installation. For example, on a 64-bit operating system you must
manually grant full permission on HKLM\Software\Wow6432Node before
a 32-bit DB2 Connect Personal
Edition product can be successfully installed.
Note: If
a non-Administrator user account is going to do the product installation,
then the VS2005 runtime library must be installed before attempting
to install a DB2® product. The
VS2005 runtime library is needed on the operating system before the DB2 product can be installed. The
VS2005 runtime library is available from the Microsoft runtime library download web
site. There are two choices: choose vcredist_x86.exe for
32-bit systems or vcredist_x64.exe for 64-bit
systems.
System shortcuts must be changed to user shortcuts for the non-Administrator
install. Moreover, since services are required to install any of the DB2 Connect products, but
cannot be created without administrative authority, services that
would be automatically started are run as processes when a non-administrator
installs.
The following are installation situations you might encounter in
an environment where both administrator and non-administrator installations
exist:
- A non-Administrator has installed DB2 Connect, and then an Administrator
attempts to install DB2 Connect on
the same system. The Administrator will get a message that the product
is already installed. The Administrator does have the authority to
uninstall and reinstall the product to get around this issue.
- A non-administrator has installed DB2 Connect, and then a second non-Administrator
attempts to install DB2 Connect on
the same system. In this scenario, the installation will fail, and
return an error message that the user must be an Administrator to
install the product.
- An Administrator has installed DB2 Connect, and then a non-Administrator
attempts to install DB2 Connect on
the same system. In this scenario, the install will fail, and return
an error message that the user must be an Administrator to install
the product. An Administrator always has the authority to uninstall
or reinstall.
- Non-Administrator users cannot uninstall a DB2 product. Those non-Administrator users on
a Windows Vista (and later)
operating system can uninstall a DB2 product.
